Determination of the micro stress field in composite by homogenization method

Abstract

The objective of this study is to investigate the local stress fluctuation in two-phase composite by homogenization method. The composite was described by homogeneous macro structure and periodical micro structure simultaneously and the mechanical response of the composite can be described based on both macro and micro dimensional scales. Micro and macro homogenization problems can be formulated. The effective material properties of the composite and the local stress field in the microstructure of the composite can be determined by solving these equations.
