本文通过实验和有限元分析 (FEA) 方法报告了机织织物的穿刺行为。实验方法在准静态条件下测试了平纹机织、2/2斜纹机织和2/1斜纹机织三种机织物的穿刺性能，获得了织物的穿刺载荷-位移曲线。还观察了穿刺损伤形态。在有限元分析中，在微观结构水平上计算了穿刺损伤的演变，并与实验方法进行了比较。实验方法和有限元分析方法之间存在良好的一致性。从有限元分析结果发现，刺穿损伤包括三个阶段：织物张力、纬纱和经纱滑移、断纱和拔出。还发现，对于三种机织物，穿刺作用在交织点或交织点之间几乎没有差异。预计这样的研究可以为经常遭受刺穿损坏的技术机织物的设计提供指导，例如土工布、簇绒地毯、背景层和柔性管道。
This paper reports the puncture behaviors of woven fabrics from experimental and finite element analyses (FEAs) approaches. In the experimental approach, the puncture behaviors of three kinds of woven fabrics, plain woven, 2/2 twill woven, and 2/1 twill, were tested under quasi-static conditions and the puncture load-displacement curves of the fabrics were obtained. The puncture damage morphologies were also observed. In FEA simulation, the puncture damage evolutions were calculated at the microstructure level and compared with those in experimental approach. Good agreements between the experimental and FEA approaches were found. From the FEA results, it was found that the puncture damage includes three stages: fabric tension, weft and warp yarn slippage, and yarn breakage and pullout. It was also found that there are almost no differences when the puncture acts at the interweaving point or between interweaving point for the three kinds of woven fabric. It is expected that such an investigation could provide guidance to the design of technical woven fabrics, such as geotextiles, tufted carpet the background layer, and flexible pipeline tubes, which often suffer from the puncture damages.
