The Effects of Interfacial Properties on the Mechanical Behavior of Layered Aluminum Matrix Composites

Abstract

Al/SiC-composites are not only ajfected by inelastic deformation processes in the metallic matrix but also by debonding occurring at the fiber-matrix-interface. Therefore a viscoplastic material law including damage evolution and growth, as well as a cohesive zone model for the interface, are integrated into a finite element technique. By this the influence of interfacial characteristics on the stress-strain behavior of a laminated Al/SiC-composite is ezramined.
