这份报纸建议一个新分析答案预言 shear 模量一二维(2D ) 平凡编织织物(PWF ) 为直角的交叉的相互作用的合成财务搁浅与联合砍包括不仅相对弯曲而且扭转的变丑模式,等等。在一个 micromechanical 单位房间的二支直角的纱是弄弯横梁,一条路径由使用正弦曲线形状功能描绘了被理想化。内部力量和宏观的变丑由纱家庭带了,和宏观砍 PWF 的模量借助于基于 micromechanics 的一条种类精力途径被导出。对三种 2D 恰当的试验性的数据的三个集合直角的 PWF composites 被实现了验证新模型。从新模型的计算也与由在更早的文学使用二个模型的那些相比。试验性的结果从新模型与预言相关很好,这被显示出。
This paper proposes a new analytical solution to predict the shear modulus of a two-dimensional(2D) plain weave fabric(PWF) composite accounting for the interaction of orthogonal interlacing strands with coupled shear deformation modes including not only relative bending but also torsion,etc.The two orthogonal yarns in a micromechanical unit cell are idealized as curved beams with a path depicted by using sinusoidal shape functions.The internal forces and macroscopic deformations carried by the yarn families,together with macroscopic shear modulus of PWFs are derived by means of a strain energy approach founded on micromechanics.Three sets of experimental data pertinent to three kinds of 2D orthogonal PWF composites have been implemented to validate the new model.The calculations from the new model are also compared with those by using two models in the earlier literature.It is shown that the experimental results correlate well with predictions from the new model.
