Abstract

Based on the small parameter asymptotic homogenization theory, this article adopts the technology of digitized
cell-based finite element method (DCB-FEM) to establish the digital cell-based mechanics analysis model of
three-dimensional 4-directional braided composite material, analyzes and calculates the equivalent elasticity
performance of 3D braided composite material using homogenization method, and the results show a good agreement with the experimental data.
