研究了编织丝网材料的力学特性，以表征这类材料在拉伸条件下的弹塑性行为。该研究的重点是一种具有代表性的316 L不锈钢（316 L SS）325 × 2300 twill-dutch编织丝网，该丝网通常用作水回收、空气过滤等应用中的精细过滤介质，并作为与爆炸物痕量检测设备结合使用的拭子棒的关键部件。采用力学实验和三维有限元模型研究了编织丝网在单轴拉伸条件下的宏观和细观力学行为。这种材料的机械响应的取向依赖性的参数研究已经进行，它涉及材料的性质，如弹性模量，屈服强度等材料取向。棘轮型拉伸试验也进行了类似的取向研究，并提出了一个基本的损伤模型的编织丝网的基础上连续损伤力学。通过有限元方法研究了钢丝网的弹塑性行为，并观察了局部塑性应变与远程施加的位移之间的关系。
The mechanics of a woven wire mesh material are investigated to characterize the elasto-plastic behavior of this class of materials under tensile conditions. The study focuses on a representative 316 L stainless steel (316 L SS) 325 × 2300 twill-dutch woven wire mesh typically used as a fine filtration media in applications such as water reclamation, air filtration, and as a key component in swab wands used in conjunction with explosive trace detection equipment. Mechanical experiments and a 3D finite element model were employed to study the macro-scale and meso-scale mechanical behavior of the woven wire mesh under uniaxial tensile conditions. A parametric study of the orientation dependence of the mechanical response of this material has been carried out, which relates material properties such as elastic modulus, yield strength, etc. to material orientation. Ratcheting type tensile tests are also performed in a similar orientation study, and an elementary damage model is presented for the woven wire mesh based on continuum damage mechanics. The elasto-plastic behavior of the wire mesh is studied via the finite element method, and observations are made relating localized plastic strain to remotely applied displacements.
