Micromechanical analyses on rubber modified epoxy resin are presented. In rubber modified epoxy resin, rubber particles are contained in Epoxy matrix. Epoxy can be regarded as a brittle matrix material and dose not undergo much nonlinear deformation. It has been seen in literature that Epoxy undergoes a considerable amount of nonlinear deformation when it is mixed with rubber. Such a material is called rubber modified Epoxy resin. It has also pointed out in literature that the primary cause of nonlinear deformation is the cavitations (fracture) of rubber particles which are embedded in Epoxy matrix. In this paper, we point out that that the effects of residual stress which is induced in curing process has a significant contributions in the deformation mechanisms of rubber modified Epoxy resin. Analyses are carried out using a classical method of micromechanics and a BE (boundary element) based homogenization method.
