Effects of interference between micro damage and phase transformation occuring due to stress interaction among particle inclusions

Abstract

Stress interactions occurring between dispersed dispersed inclusions in the composite material cause nonuniform as well as intense stress distributions in the matrix phase. The meso-local phenomena of nonlinear material characteristics caused by the local interaction will further cause with each other a secondary interaction between the multiple nonlinear material behaviors. In this paper, the damage and the phase transformation phenomena interfering with each other are investigated by FEM meso-mechanics analysis, and also the development of the macro constitutive modeling incorporating the both effects is attemped.
