Experimental results show that the void volume fractions of these materials increase as strain increases,and the void volume fraction increases more rapidly for material with more carbonide particles than that with fewer carbonide particles.Theoretical analyses show that the influence of void damage on mechanical behaviours can be considered as strain softening. Based on this consideration,the analytical expressions of equivalent strain hardening exponent and fracture strain for plastic damaged materials with second-phase particles were derived, the results calculated with these expressions are in good agreement with the experimental results.
