The elastoplasticity behavior of wire in inhomogeneous woven metal mesh

This paper discusses the plastic behavior of wires in metal mesh for discussing the structure of woven warp and weft with their inhomogeneous and homogeneous by using finite element method (FEM). In the FEM, an isotropic plasticity is adopted as constitutive model of woven wire, but inhomogeneous between warp and weft is discussed to evaluate the mechanical characteristic of the mesh as an industrial products. Here, fundamental relation of power law hardening rule is adopted to represent the plasticity, but physical parameters of it will be controlled for the discussion of plasticity on mesh weaving. The inhomogeneous of mesh structure is one of key technology to control the product quality of metal mesh, and the mechanics of plasticity of metal mesh should be discussed to develop the product. In this report, the difference of material parameters and tension during weaving process is targeted on the discussion. Some conditions on the wires of warp and weft are examined in weaving process by FE
