An abaqus plugin for homogenization of woven composite fabric

The mechanical properties of a woven composite are affected by the mechanical and geometric properties ofits components. In a large-scale analysis, considering the parameters related to the components will increase the timeand cost of the analysis. In order to avoid these conditions, the mechanical properties of the composite material arehomogenized by considering the characteristics of the components. In this article, a woven composite parameters isdetermined by homogenization of its component properties using the finite element method in Abaqus software. In thismethod, a representative volume element is modeled according to the geometric and mechanical characteristics of thewarp, weft and matrix. Then, by using ۹ steps of simulation of simple tension and simple shear test, the energy stored inthe element and the ۹ components of the stiffness matrix of the composite material is calculated. This algorithm isintegrated and present in an abaqus plugin.
