Effects of dilatation phase transformation on target strength of ceramic materials

摘要

The effect of dilatational phase transformation on the target strength of ceramic materi- als are investigated based on Tate's model. The constitutive behavior of materials in different regions (elastic, cracked, plastic and phase transformation)are taken into account. It is found that, with a proper choice of material parameters, the dilatational phase transformation can increase effectively the target strength R. This would be of importance in penetration-resistance design.
