In this paper, formulations for the analysis of particulate composite materials whose particles undergo particle fracture/interface debonding or stress induced phase transformation. The formulations are developed based on a boundary element based homogenization technique where the influences of differences in elastic properties between matrix and particles and transformation strains are accounted for by using analytical expressions. Macroscopic stresses are computed based on the homogenization method. Hundreds of particles which undergo particle fracture/interface debonding or stress induced phase transformation are placed in a unit cell for the homogenization analysis. Thus,quasi-smooth macroscopic stress-strain curves can be generated based on particle fracture/interface debonding or phase transformation criterion for each particle. 650, 125, 35 and 3 particle modeles are analyzed in this paper.
