During the present research, the following have been accomplished 1 The separate dilatationaldeviatoric damage constitutive model was proposed along with a method to extract its material parameters from one-dimensional stress-strain curve. The damage model was implemented in the s-FEM computer program. 2 S-FEM formulation with the cohesive zone model has been proposed and has been implemented in the s-FEM program. 3 S-FEM analyses on particulate composite materials, with assuming the matrix damage and dewetting between the particles and matrix material, has been carried out. Some characteristic behavior of damages in the particulate composite materials has been revealed.
