Micromechanical modeling of damage in particle-reinforced composites
Additional Document Info
Metals reinforced with particles or short fibers of ceramics exhibit a variety of failure modes during the application of monotonic or cyclic loads. The analyses are carried out using two-dimensional axisymmetric and plane strain unit cell models. The reinforcement is characterized as an isotropic elastic solid and the ductile matrix as an isotropically hardening viscoplastic solid except when matrix ductile failure is considered. Then, the matrix material is characterized by a constitutive relation for progressively cavitating plastic solids.
