This article attempts to bring an enhanced insight into the analysis of in-plane shear behavior of woven fabrics. Two common methods have been used to characterize the shear behavior of woven preforms, namely the Bias Extension (BE) and Picture Frame (PF) tests. In spite of the identical macro-scale shear deformation of fabrics in these two characterization procedures, the current study demonstrates that their underlying micro- and meso-scale deformation mechanisms are quite distinct. The trellising mechanism, which is based on the well-known Pin-Joint Theory (PJT), has been regarded for a long time as the sole model to describe the meso-scale deformation of woven fabrics in both the BE and PF tests. Throughout this article, this mechanism is challenged for the PF test by undertaking a multi-scale analysis along with a critical review and integration of the previous experimental, analytical, and numerical studies. Intra-yarn shear, which has not been fully understood yet, is substantiated as a potential meso-level deformation mechanism occurring in the PF test. Accordingly, a new meso-level deformation model is proposed and compared with the trellising shear pattern in the BE setup. Afterward, the comparison is extended from meso-level to macro-level in order to provide more in-depth hypotheses for explaining differences reported in the literature between the shear characteristics of fabrics using BE and PF tests. Finally, some guidelines have been sought to select more reliable characterization method given a forming process.

纱内剪切在机织织物多尺度综合变形分析中的作用:综述。

本文试图为机织织物的面内剪切行为分析提供增强的见解。两种常用的方法已用于表征机织预成型坯的剪切行为,即偏压延伸(BE)和画框(PF)测试。尽管在这两个表征过程中织物具有相同的宏观尺度剪切变形,但当前的研究表明,其潜在的微观尺度和中观尺度的变形机理是截然不同的。基于众所周知的Pin-Joint理论(PJT)的网格化机制在BE和PF测试中长期以来一直被视为描述机织织物中尺度变形的唯一模型。在整篇文章中,通过进行多尺度分析,以及对以前的实验,分析和数值研究进行严格的审查和整合,对PF测试而言,该机制受到了挑战。纱内剪切(尚未完全理解)被证实为在PF测试中可能发生的细观水平变形机制。因此,提出了一种新的中观水平变形模型,并将其与BE设置中的格状剪切模式进行了比较。之后,将比较从介观水平扩展到宏观水平,以提供更深入的假设,以解释文献中使用BE和PF测试的织物剪切特性之间的差异。最后,已寻求一些指导方针以选择给定的成型工艺来选择更可靠的表征方法。分析和数值研究。纱内剪切(尚未完全理解)被证实为在PF测试中可能发生的细观水平变形机制。因此,提出了一种新的中观水平变形模型,并将其与BE设置中的格状剪切模式进行了比较。之后,将比较从介观水平扩展到宏观水平,以提供更深入的假设,以解释文献中使用BE和PF测试的织物剪切特性之间的差异。最终,已经寻求一些指导方针以在给定成型过程的情况下选择更可靠的表征方法。分析和数值研究。纱内剪切(尚未完全理解)被证实为在PF测试中可能发生的细观水平变形机制。因此,提出了一种新的中观水平变形模型,并将其与BE设置中的格状剪切模式进行了比较。之后,将比较从介观水平扩展到宏观水平,以提供更深入的假设,以解释文献中使用BE和PF测试的织物剪切特性之间的差异。最终,已经寻求一些指导方针以在给定成型过程的情况下选择更可靠的表征方法。提出了一种新的中观变形模型,并与BE设置中的格状剪切模式进行了比较。之后,将比较从介观水平扩展到宏观水平,以提供更深入的假设,以解释文献中使用BE和PF测试的织物剪切特性之间的差异。最后,已寻求一些指导方针以选择给定的成型工艺来选择更可靠的表征方法。提出了一种新的中观变形模型,并与BE设置中的格状剪切模式进行了比较。之后,将比较从介观水平扩展到宏观水平,以提供更深入的假设,以解释文献中使用BE和PF测试的织物剪切特性之间的差异。最后,已寻求一些指导方针以选择给定的成型工艺来选择更可靠的表征方法。
