Formulation and some results for the analysis of particulate composite materials using a boundary element (BE) approach are presented. BE approach, which is proposed in this paper, is developed by combining integral equations and analytical solutions for ellipsoidal inclusions such as Eshelby's tensor. The homogenization method is then adopted to carry out meso-scale analyses. Present approach does not require any interior discretizations and is quite efficient even when there are a number of particles in the analysis region. Furthermore, by using present approach, the detailed meso-stress field in particulate composite material can be analyzed and visualized. Some numerical results are presented.
