COMPUTATIONAL MODELING OF DEFORMATION AND DAMAGE IN PARTICLE-REINFORCED COMPOSITES

摘要

The micromechanisms of deformation and fracture in particle-reinforced composites are studied through the finite element simulation of 3D multiparticle cubic cells. The simulations provided new insights on the role played by reinforcement clustering and damage (particle fracture, interface decohesion, ductile matrix failure) on the overall composite tensile response as well as on the micromechanisms of damage nucleation and growth.
