Abstract
In this paper evolution equations for the C(t)-integral and the crack-tip opening displacement CTOD are presented for elastic-viscoplastic material behavior and monotonic loading. The evolution equations account for the temperature dependence of the elastic, plastic and viscous material properties. Additionally, an implicit integration algorithm is presented and validated by using finite element simulations.
