摘 要: | In this paper, a incremental form of constitutive laws for creeping studies are proposed. The equations are based on the concept of creep hardening surface. Damage effects were introduced to the new constitutive relations to study solids creeping effects with pre-ex-isting damages. The present formula is easy to be adopted into other numerical procedures such as finite element methods.
