Micromechanical model for the analysis of unidirectional elastoplastic composites subjected to 3D stresses

摘要

A numerical model to predict the global response of unidirectional fiber reinforced composites subjected to general 3D stresses is presented. The reinforcing array consists of equal fibers of circular cross section, that are evenly arranged according to a regular hexagonal pattern. The problem is analyzed within the framework of the micromechanical theory of heterogeneous, periodic materials. The global response of the composite is determined through the analysis of any representative volume element (RVE).
