Numerical Simulation on Mechanical Properties of SiC/Al Co-Continuous Composites

Abstract:

Mechanical properties of the co-continuous SiC/Al composites were simulated using the ANSYS software in this paper, and Kelvin model was adopted as SiC structure. The models of various SiC contents were calculated for composites, the influences of SiC volume fraction on the interface were analyzed. Compared with the particle reinforced composites, the influences of SiC structure on the interface and strength were investigated. The results showed that the SiC volume fraction has a certain effect on the interface of composites, the incoordination of deformation of SiC and Al causes the greater stress concentration with SiC volume fraction decreases, so that interface occurs the debonding. Compared the simulation results of co-continuous composites and particle reinforced composites, two stress-distance curves show that the stress decreases with the distance from the interface increases, and two stress-strain curves prove that the co-continuous composites have higher the yield strength and the deforming resistance.
