The CRS is evaluated by solving for the material behaviors of the cure kinetics, viscoelasticity, thermal expansion, and cure shrinkage under heat transfer condition using finite element (FE) method. The geometry and CRS fields are extracted from numerous simulations and subsequently utilized in the proposed cGAN training process. With this end-to-end unsupervised learning, the cGAN model can predict the CRS with high fidelity based on the fiber random distributed microstructure and capture the variation of fiber volume fraction. In qualitative measures, peak signal to noise ratio (PSNR) and structure similarity index (SSIM) are employed for accuracy verification. Moreover, the cGAN model can also significantly reduce the computational cost and provide some insights for optimizing the manufacturing process of composites.在本作品中，我们提出了一种由条件生成对抗网络（cGAN）驱动的深度学习模型，用于快速评估和预测复合材料的固化诱导残余应力（CRS）。通过使用有限元（FE）方法求解热传导条件下的固化动力学、粘弹性、热膨胀和固化收缩等材料行为，对 CRS 进行评估。从大量模拟中提取几何形状和 CRS 场，然后将其用于拟议的 cGAN 训练过程。通过这种端到端的无监督学习，cGAN 模型可以根据纤维随机分布的微观结构高保真地预测 CRS，并捕捉纤维体积分数的变化。在定性测量中，采用峰值信噪比（PSNR）和结构相似性指数（SSIM）来验证准确性。此外，cGAN 模型还能显著降低计算成本，并为优化复合材料制造工艺提供一些启示。Experimental study on the bonding performance of engineered cementitious composites to normal concrete interface subjected to salt freeze-thaw cyclesJincheng Cao, Fangwen Wu, Lei song, Xiangyan Fan, Laijun Liu, Zirun Li, Ao Chendoi:10.1016/j.compstruct.2023.117828盐冻融循环条件下工程水泥基复合材料与普通混凝土界面粘结性能的实验研究This research aims to clarify the damage mechanism of engineered cementitious composites (ECC) to normal concrete (NC) interface under salt freeze–thaw cycles. A comprehensive analysis was conducted to investigate the effects of the interfacial type, ECC strength grade, and the number of salt freeze–thaw cycles on the interfacial bonding performance. The results showed that interfacial failure modes were significantly affected by the interfacial types. Two failure modes (direct shear and fatigue) were observed in the salt freeze-thaw test, and the other two failure modes (bonding material and matrix material) were observed in the direct shear test. Meanwhile, the interfacial shear strength was negatively correlated with the cycle number. Increasing the ECC strength could effectively improve the interfacial bonding performance, especially for specimens with ultra-high-performance concrete (UHPC) bonding. Finally, an interfacial bond–slip degradation model was proposed, which could be used to predict the interfacial salt freeze-thaw damage accurately.本研究旨在阐明盐冻融循环条件下工程水泥基复合材料（ECC）与普通混凝土（NC）界面的破坏机理。综合分析了界面类型、ECC强度等级和盐冻融循环次数对界面粘结性能的影响。结果表明，界面破坏模式受界面类型的影响很大。在盐冻融试验中观察到两种失效模式（直接剪切和疲劳），在直接剪切试验中观察到另外两种失效模式（粘接材料和基体材料）。同时，界面剪切强度与循环次数呈负相关。提高 ECC 强度可有效改善界面粘结性能，尤其是对于采用超高性能混凝土（UHPC）粘结的试样。最后，提出了界面粘结滑动退化模型，该模型可用于准确预测界面盐冻融破坏。Gradient Shear Thickening Gel/ Stacked Kevlar Multi-layer Armor with Enhanced Impact Attenuation PropertyFeng Chen, Zhen-Hua Tang, Yu Zhu, Jian-Qiang Deng, Yuan-Qing Li, Ya-Qin Fu, Shao-Yun Fudoi:10.1016/j.compstruct.2023.117829梯度剪切增厚凝胶/叠层凯夫拉纤维多层装甲，具有更强的冲击衰减性能Realizing highly-efficient energy absorbing performance in soft body armor, yet with lightweight feature, has always been an eternal subject for personal protective equipment. This work reports a gradient shear thickening gel (STG)/stacked Kevlar (GS-STG/Kevlar) multi-layer fabric armor with both lightweight feature and excellent impact attenuation performance. Firstly, STG is prepared by mechanical blending and chemical crosslinking and then coated on Kevlar fabrics, and afterwards STG-coated Kevlar multi-layer fabrics with gradient STG distribution in the thickness direction are fabricated. Single yarn pull-out test demonstrates that the friction between Kevlar yarns is greatly increased after STG treatment. Moreover, tribological testing also indicates that the friction coefficient of Kevlar fabrics is improved by coating STG. Furthermore, low- and high-speed impact experiments are conducted, and the results demonstrate that the GS-STG/Kevlar composite exhibits the best impact attenuation property when compared with multilayered Kevlar fabrics and uniformly stacked STG/Kevlar fabrics under the same impact conditions. The increased friction and stiffening effect by STG, and the gradient stacking strategy are responsible for the great improvement in the impact attenuation performance of GS-STG/Kevlar multi-layer armors. This study provides an effective methodology for achieving soft body armors with lightweight and high impact attenuation properties for personal impact protection.在软质防弹衣中实现高效的能量吸收性能，同时兼顾轻质特性，一直是个人防护装备的永恒课题。本研究报道了一种梯度剪切增稠凝胶（STG）/叠层凯夫拉纤维（GS-STG/Kevlar）多层织物装甲，兼具轻质特性和优异的冲击衰减性能。首先，通过机械混合和化学交联制备 STG，然后将其涂覆在凯夫拉纤维上，最后制成 STG 在厚度方向上梯度分布的 STG 涂覆凯夫拉多层纤维装甲。单根纱线拉出试验表明，经过 STG 处理后，凯夫拉纱线之间的摩擦力大大增加。此外，摩擦学测试也表明，涂覆 STG 后，凯夫拉纤维的摩擦系数得到了改善。此外，还进行了低速和高速冲击实验，结果表明，在相同的冲击条件下，GS-STG/Kevlar 复合材料与多层 Kevlar 织物和均匀堆叠的 STG/Kevlar 织物相比，具有最佳的冲击衰减性能。STG 增加的摩擦和刚度效应以及梯度堆叠策略是 GS-STG/Kevlar 多层装甲冲击衰减性能大幅提高的原因。这项研究为实现轻质、高冲击衰减性能的软体护甲提供了一种有效的方法，可用于人身冲击防护。Hygrothermal effects on fatigue delamination behavior in composite laminatesLiaojun Yao, Jiexiong Wang, Yonglyu He, Xiuhui Zhao, Xiangming Chen, Jurui Liu, Licheng Guo, R.C. Alderliestendoi:10.1016/j.compstruct.2023.117830湿热效应对复合材料层压板疲劳分层行为的影响Fatigue delamination growth (FDG) is an important failure in composite structures during their long-term operations. Hygrothermal aging can have significant effects on interlaminar resistance. It is therefore really necessary to explore FDG behavior in composite laminates with hygrothermal aging. Dynamic mechanical thermal analysis (DMTA), mode I FDG experiments and fractographic examinations were conducted to fully investigate hygrothermal aging effects and the corresponding mechanisms on FDG behavior. The DMTA results indicated that environmental aging can induce obvious Tg decrease. Mode I experimental fatigue data interpreted via different Paris-type correlations demonstrated that: Bridging has obvious retardation effects on FDG behavior via the Paris interpretations; The modified Paris relation can well characterize the intrinsic FDG behavior around the crack front; The use of the two-parameter Paris-type relation can appropriately account for R-ratio effects, contributing to a master resistance curve in determining mode I FDG behavior. According to these interpretations, it can be concluded that hygrothermal aging can have adverse effects on mode I FDG behavior. SEM examinations demonstrated that moisture absorption can cause fibre/matrix debonding and resin matrix pores/voids in the composite. However, no obvious difference in damage mechanisms was identified in mode I fatigue delamination for composite with/without environmental conditioning. Both fibre/matrix debonding and matrix brittle fracture were identified on fatigue fracture surfaces. Accordingly, it was concluded that fibre/matrix interface and matrix degradation induced by water absorption were the main reasons for a faster mode I fatigue crack growth in environmental aged composite.疲劳分层生长（FDG）是复合材料结构长期运行过程中的一个重要故障。湿热老化会对层间阻力产生重大影响。因此，有必要对湿热老化复合材料层压板的 FDG 行为进行研究。为了全面研究湿热老化对 FDG 行为的影响和相应机制，我们进行了动态力学热分析（DMTA）、模式 I FDG 实验和断裂学检查。DMTA 结果表明，环境老化会导致 Tg 下降。通过不同的巴黎型相关性解释的模式 I 实验疲劳数据表明通过巴黎关系式解释，桥接对 FDG 行为具有明显的延缓效应；修正的巴黎关系式可以很好地描述裂纹前沿周围的固有 FDG 行为；使用双参数巴黎关系式可以适当地考虑 R 比率效应，有助于在确定模式 I FDG 行为时形成主电阻曲线。根据这些解释，可以得出结论：湿热老化会对模式 I FDG 行为产生不利影响。扫描电子显微镜检查表明，吸湿会导致复合材料中的纤维/基质脱粘和树脂基质孔隙/空洞。然而，在有/无环境调节的复合材料中，模式 I 疲劳分层的损坏机制并无明显差异。在疲劳断裂面上发现了纤维/基质脱粘和基质脆性断裂。由此得出结论，吸水引起的纤维/基质界面和基质降解是环境老化复合材料中模式 I 疲劳裂纹增长较快的主要原因。Investigating the Influence of High-Void Content on the Impact and Post-Impact Properties of Flax/Epoxy Composite Laminates with Different Stacking ConfigurationsAbdelhadi Hadj-Djilani, Lotfi Toubal, Habiba Bouguerara, Redouane Zitounedoi:10.1016/j.compstruct.2023.117832研究高类固醇含量对不同堆叠配置的亚麻/环氧复合材料层压板的冲击和冲击后性能的影响Defects in composite materials, such as voids, significantly impact their long-term performance and should be carefully considered in the design process of engineering structures. This study investigates the effects of high void content on the impact and post-impact properties of pure Flax/Epoxy (FE) composite laminates. Three main configurations, namely cross-ply (CFE), angle-ply FE (AFE), and quasi-isotropic FE (QFE), are examined using drop-weight impact and three-point bending tests. The results reveal distinct behavior among the configurations. The drop-weight impact test results show that the AFE configuration exhibits 3.5% and 6.45% higher impact resistance compared to CFE and QFE, respectively. to the increase of the impact energy to 15J amplifies the differences to 9.31% and 19.11 %. Also, post-impact flexion tests demonstrate a significant decline in flax composite resistance by 14% for CFE, 26% for QFE, and AFE. Furthermore, the overall impact and flexural properties of the FE composites are not significantly affected by the void content. However, it has a major impact on the damage mechanism that is ispected visually and through X-ray tomography, emphasizing the importance of considering the void content in the design and analysis of such flax composites. The proposed numerical model to predict the onset of damage and damage evolution in these composite materials under low velocity impact show a good greement with the experimental results.复合材料中的缺陷（如空隙）会严重影响其长期性能，因此在工程结构设计过程中应慎重考虑。本研究探讨了高空隙含量对纯亚麻/环氧（FE）复合材料层压板的冲击性能和冲击后性能的影响。通过落重冲击和三点弯曲试验，研究了三种主要结构，即交叉层（CFE）、角层 FE（AFE）和准各向同性 FE（QFE）。试验结果表明，这些结构之间存在明显差异。落重冲击试验结果表明，与 CFE 和 QFE 相比，AFE 配置的抗冲击性分别高出 3.5% 和 6.45%。此外，冲击后的弯曲测试表明，CFE、QFE 和 AFE 的亚麻复合材料抗冲击性显著下降了 14%、26%。此外，空隙含量对 FE 复合材料的整体冲击和弯曲性能影响不大。然而，它对通过视觉和 X 射线断层扫描观察到的损伤机制有重大影响，这强调了在设计和分析此类亚麻复合材料时考虑空隙含量的重要性。为预测这些复合材料在低速冲击下的损伤开始和损伤演变而提出的数值模型与实验结果显示出良好的一致性。Investigation into quasi-static compressive behaviors of several kinds of honeycomb like structures in three axial directionsGuijia Gao, Haibiao Lu, Chunhui Sha, Weili Ren, Yunbo Zhong, Zuosheng Leidoi:10.1016/j.compstruct.2023.117833几种蜂窝状结构在三个轴向的准静态抗压行为研究The natural beesʼ honeycombs maintain long-term structural stability in harsh environments, employing a highly material-efficient approach. However, the reasons remain somewhat ambiguous. To clarify the stabilization mechanism and investigate quasi-static compression responses of double-layer ordered cellular structures, honeycomb, Tóth and single-layer cellular structures with a relative density (ρr) of 25.84% were fabricated using 3D printing technology. Then, quasi-static compression experiments in three directions were conducted. Further, a numerical study was conducted to uncover the stabilization mechanism and effect of ρr on compressive behaviors. Results revealed that the stabilization mechanism was mainly attributed to bearing load priority of intermediate layer and its inhibition on formation of plastic hinges. A relative density of 5.17% served as a transition point for deformation mode, beyond which honeycomb and Tóth structures exhibited stronger in-plane compressive strength at expense of less sacrificed out-of-plane compressive strength, below which they both exhibited more stable compressive curves compared to single-layer cellular structures, which were favorable for energy absorption. This study clarifies the stability mechanism of beesʼ honeycombs and addresses the lack on compression behaviors of double-layer ordered cellular structures. Moreover, it introduces two available bionic structures with controllable deformation modes to expand the application of single-layer cellular structures.天然蜜蜂的蜂巢在恶劣的环境中保持着长期的结构稳定性，采用了一种非常节省材料的方法。然而，其中的原因仍然有些模糊。为了阐明稳定机制并研究双层有序蜂窝结构的准静态压缩响应，利用三维打印技术制作了相对密度（ρr）为25.84%的蜂窝、托斯和单层蜂窝结构。然后，进行了三个方向的准静态压缩实验。此外，还进行了数值研究，以揭示稳定机制和ρr对压缩行为的影响。结果表明，稳定机制主要归因于中间层的承载力优先及其对塑性铰形成的抑制作用。5.17%的相对密度是变形模式的一个过渡点，超过该点，蜂窝结构和托特结构表现出更强的平面内抗压强度，但牺牲的平面外抗压强度较小，低于该点，与单层蜂窝结构相比，它们都表现出更稳定的抗压曲线，有利于能量吸收。这项研究阐明了蜜蜂蜂窝的稳定机制，并解决了双层有序蜂窝结构抗压行为方面的不足。此外，它还介绍了两种具有可控变形模式的仿生结构，以扩大单层蜂窝结构的应用范围。The alignment of CNTs perpendicular to electric filed resulted in effective electrothermal de/anti-icing performance at high voltage for CNT/XLPE compositesXiaoli Wu, Yunyi Li, Ting Yin, Yijun Liao, Site Mo, Wanxia Huangdoi:10.1016/j.compstruct.2023.117835垂直于电场的 CNT 排列使 CNT/XLPE 复合材料在高压下具有有效的电热除冰/防结冰性能The composite in transverse direction to the alignment is considered as completely insulating and unsuitable for utilization in de-icing system. Here, we found that the composite in transverse direction to the alignment exhibits excellent electrothermal performance at high voltage, for the first time. Furthermore, we compared and investigated the electrical and electrothermal performance of the aligned and random non-percolative CNT/crosslinked polyethylene (XLPE) composites at high voltage. A temperature increase of 7.5–72.7 ℃ at a record high voltage of 900–3100 V is reached for the aligned CNT/XLPE composites. The filed emission at high voltage enables the electron to transfer along the CNTs radial direction, resulting in joule heating for the aligned CNT/XLPE composites in transverse direction to the alignment. Besides, the non-percolative structure contributes a temperature increase of 8.2–40.1 ℃ at applied voltages of 900–2800 V to random CNT/XLPE composites. The high applied voltages is significantly higher than rGO-based composites. More importantly, effective de-icing and anti-icing performance at high voltage of 900–2800 V are achieved for the random non-percolative and aligned CNT-based composites at −20 ℃. These results demonstrate the potential of applying the CNT/XLPE composites in de/anti-icing system of transmission-lines and other fields requiring joule heating at high voltage.横向排列的复合材料被认为是完全绝缘的，不适合用于除冰系统。在这里，我们首次发现，在高电压下，横向排列的复合材料表现出优异的电热性能。此外，我们还比较并研究了有序排列的 CNT/交联聚乙烯（XLPE）复合材料与无序排列的 CNT/交联聚乙烯（XLPE）复合材料在高压下的电气和电热性能。在 900-3100 V 的创纪录高压下，排列的 CNT/XLPE 复合材料的温度升高了 7.5-72.7 ℃。高电压下的锉射使电子沿 CNT 的径向转移，从而导致对齐 CNT/XLPE 复合材料在对齐的横向上产生焦耳热。此外，在施加 900-2800 V 的电压时，非气蚀结构会使无规 CNT/XLPE 复合材料的温度升高 8.2-40.1 ℃。高应用电压明显高于基于 rGO 的复合材料。更重要的是，在 900-2800 V 的高电压下，无规非腐蚀性和排列有序的 CNT 复合材料在 -20 ℃ 下实现了有效的除冰和防冰性能。这些结果证明了将 CNT/XLPE 复合材料应用于输电线路除冰/防冰系统以及其他需要在高压下进行焦耳加热的领域的潜力。Composites Part A: Applied Science and ManufacturingProcess-Induced Residual Stress in a Single Carbon Fiber Semicrystalline Polypropylene Thin FilmNithin K. Parambil, Branndon R. Chen, John W. Gillespiedoi:10.1016/j.compositesa.2023.107969单碳纤维半结晶聚丙烯薄膜中的工艺诱导残余应力During the processing of semicrystalline thermoplastic composites, various models for the prediction of residual stress have been proposed but experimental validation is limited. In this study, a modeling framework is developed to predict the evolution of residual stress in a single carbon fiber embedded in a semicrystalline polypropylene thin film subjected to non-isothermal cooling. Validation is based on in-situ measurement of axial fiber strain after processing using micro-Raman Spectroscopy. A material model for polypropylene (50% equilibrium crystallinity) is presented that incorporates the effects of non-isothermal cooling on crystallinity-dependent resin shrinkage and crystallinity-dependent resin modulus from the amorphous polymer melt to room temperature. The evolution of residual stress is calculated using a finite element (FE) model with a user-developed subroutine incorporating the resin material models. Single-fiber polypropylene films are fabricated using a range of fiber pretension levels to prevent fiber waviness during cooling and to induce a wide range of axial strain levels in the fiber for model validation. The fiber axial strain was measured over the length of the fiber, from the free edge into the bulk, capturing the ineffective length region where strain builds up and plateaus. A good correlation has been obtained between the model results and the in-situ measurements of axial compression strain in the fiber. A key finding was the importance of including temperature-dependent resin modulus and that the contribution of crystallinity shrinkage to residual strain in the carbon fiber is relatively low. The model developed in this study is also compared to residual stress models in the literature which shows the importance of including the effects of crystallization and cooling rate on temperature and crystallinity-dependent modulus and resin shrinkage for accurate predictions.在半结晶热塑性复合材料的加工过程中，人们提出了各种预测残余应力的模型，但实验验证却很有限。本研究建立了一个建模框架，用于预测嵌入半结晶聚丙烯薄膜中的单根碳纤维在非等温冷却条件下的残余应力演变。验证基于使用显微拉曼光谱法对加工后纤维轴向应变的现场测量。介绍了聚丙烯（50% 平衡结晶度）的材料模型，该模型包含了非等温冷却对从无定形聚合物熔体到室温的结晶度相关树脂收缩和结晶度相关树脂模量的影响。残余应力的演变是通过有限元（FE）模型和用户开发的包含树脂材料模型的子程序计算得出的。在制作单纤维聚丙烯薄膜时，使用了一系列纤维预拉伸水平，以防止纤维在冷却过程中产生波纹，并在纤维中产生各种轴向应变水平，以验证模型。纤维的轴向应变是在纤维长度上测量的，从自由边缘到纤维体，捕捉到了应变累积和稳定的无效长度区域。模型结果与纤维轴向压缩应变的现场测量结果之间具有良好的相关性。一个重要的发现是，包含随温度变化的树脂模量非常重要，而且结晶收缩对碳纤维残余应变的影响相对较小。本研究中开发的模型还与文献中的残余应力模型进行了比较，结果表明，要进行准确预测，必须将结晶和冷却速度对温度的影响以及与结晶度相关的模量和树脂收缩包括在内。Composites Part B: EngineeringTensile mechanical properties and damage analysis of layered woven GFRP composite boltsJintong Zhang, Tao Yang, Yu Du, Renyu He, Chang Liudoi:10.1016/j.compositesb.2023.111155分层编织 GFRP 复合材料螺栓的拉伸力学性能和损伤分析Composite bolts have become one of the research focuses in screw threads joints due to their lightweight, high-strength, and wave transmission properties. We elucidate the differences in tensile properties, damage processes, and tensile failure forms between two types of layered woven GFRP composite bolts through tests and numerical simulations. It was found that the tensile strength of layered plain woven bolts is 40% higher than layered twill woven bolts. The failure forms of both types of bolts are related to their layered woven structure. The fracture surface of plain bolts is planar, while the fracture surface of twill bolts is apex shaped. Subsequently, a refined thread stretching model was established to study the effect of loading speed on the tensile property of screw threads. It was found that the tensile strength of plain woven screw threads and twill woven screw threads at a loading speed of 1 mm/min was 11% and 6% higher than that at 3 mm/min, respectively. The results show that the bolts and screw threads with layered plain woven have stronger tensile strength than those with layered twill woven, and a decrease in loading speed within a certain range can improve the tensile strength of the screw threads.复合材料螺栓因其轻质、高强、透波等特性已成为螺纹接头的研究重点之一。我们通过试验和数值模拟，阐明了两种分层编织 GFRP 复合材料螺栓在拉伸性能、损伤过程和拉伸失效形式上的差异。试验发现，分层平纹编织螺栓的拉伸强度比分层斜纹编织螺栓高 40%。两种螺栓的破坏形式都与其分层编织结构有关。平纹螺栓的断裂面为平面，而斜纹螺栓的断裂面为顶点形。随后，建立了精炼的螺纹拉伸模型，以研究加载速度对螺纹拉伸性能的影响。结果发现，在加载速度为 1 毫米/分钟时，平织螺纹和斜织螺纹的拉伸强度分别比加载速度为 3 毫米/分钟时高 11% 和 6%。结果表明，分层平纹编织的螺栓和螺纹比分层斜纹编织的螺栓和螺纹具有更强的抗拉强度，在一定范围内降低加载速度可以提高螺纹的抗拉强度。Composites Science and TechnologyPreparation of superhydrophobic shape memory composites with uniform wettability and morphing performanceXinlin Li, Bin Zhan, Xueting Wang, Yan Liu, Yanju Liu, Jinsong Lengdoi:10.1016/j.compscitech.2023.110398 制备具有均匀润湿性和变形性能的超疏水形状记忆复合材料Superhydrophobic shape memory surfaces have attracted much attention in recent years, as they can intelligently control surface wettability. However, less research has focused on the development of superhydrophobic shape memory materials that can maintain uniform wettability in any morphing shape. It is common in nature that species such as lotus leaves and kingfisher show good superhydrophobicity in any movement under/on water. Based on this inspiration, this work presents a novel superhydrophobic shape memory composite (SSMC) by coupling superhydrophobic coatings and shape memory epoxy composites. The SSMC exhibits excellent water repellency and self-cleaning performance regardless of how it is bent. In addition, its good shape memory effect and variable stiffness characteristics enable it to be potentially used as deployable marine structures and morphing skin of aquatic unmanned aerial vehicles. On the other hand, the SSMC also offers good anti-icing properties and mechanical/chemical robustness that enhance long-term service performance all year round. This research provides a fresh idea for the design of new smart superhydrophobic materials and expands applications in the field of marine and aviation facilities.超疏水形状记忆表面能够智能控制表面润湿性，因此近年来备受关注。然而，关于开发可在任何变形形状下保持均匀润湿性的超疏水形状记忆材料的研究却较少。在自然界中，荷叶和翠鸟等物种在水下/水上的任何运动都表现出良好的超疏水性。受此启发，本研究通过将超疏水涂层与形状记忆环氧树脂复合材料相结合，提出了一种新型超疏水形状记忆复合材料（SSMC）。无论如何弯曲，SSMC 都能表现出优异的憎水性和自清洁性能。此外，其良好的形状记忆效果和可变刚度特性使其有可能用作可部署的海洋结构和水上无人飞行器的变形表皮。另一方面，SSMC 还具有良好的防冰性能和机械/化学坚固性，可提高全年的长期使用性能。这项研究为新型智能超疏水材料的设计提供了新思路，拓展了其在海洋和航空设施领域的应用。来源：复合材料力学仿真Composites FEM
