Abstract

In the SiC reinforced aluminum alloy, the SiC particles or fibers are distributed in the base matrix in a random manner. These local inhomogeneous structure plays a main role in ductile deformation process. The evaluation of the strength of this metal matrix composite, the effects of these local behavior are considered. Based on the experimental observation of the fracture process, numerical models are made for FEM analyses. The effects of the stress triaxiality and local constraint on the damage process are studied and discussed. l.Introduction SiC reinforced aluminum alloy is now used widely because it has improved mechanical properties[i]. The fracture process of t
