Elastic-Plastic Analysis of Unidirectional Composites

Abstract

This paper considers the elastic-plastic analysis of unidirectional-filament reinforced composites subjected to longitudinal loading. The method of anal ysis is based on special generalized plane strain conditions, finite element techniques and Prandtl-Reuss incremental plasticity relations. The results for a boron/ aluminum composite and a boron/epoxy composite were compared to show the relation between composite behavior and the material properties of the matrix.
