Abstract
Failure of metal-matrix composites subject to monotonie tension is studied numerically. The metal-matrix material is characterized as a progressively cavitating solid. A cohesive surface characterization of the particle/matrix interface is used to allow for interfacial debonding. Additionally, particle cracking is modeled by including an initial crack, perpendicular to the tensile axis and with a cohesive surface in its initial plane to permit crack growth. Thus, the interaction between the three main failure modes in metal matrix composites, particle cracking, matrix cavitation, and interfacial debonding, can be studied. Results are presented for a plane strain unit cell model of a metal-matrix reinforced with a 20% area fraction of reinforcing particles.
