Numerical Simulations of Compression Properties of SiC/Fe-20Cr Co-Continuous Composites
The uniaxial deformation properties of a SiC/Fe-20Cr composite where both phases are continuous have been studied using the Solidwork simulation software applied the finite element method (FEM). The simulated results have shown that the composites are relatively anisotropy. Fe-20Cr matrix and SiC network ceramic exhibit different mechanical behaviour. The ultimate stress is found near the interface of composites. The configuration of SiC has relatively great influence on intensity and distribution of stress in the composite. The material behaves in a nearly bilinear manner defined by the Young’s modulus and an elastic-plastic modulus. The large deformation appears inside Fe-20Cr matrix. The elastic deformation in the ceramic is accommodated by plastic deformation in the metal phase. Fe-20Cr and SiC can restrict each other to prevent from producing the strain under the load.
