- Abstract
- This paper presents equations for estimating the crack tip characterizing parameters C(t) and J(t), for general elastic-plastic-creep conditions where the power-law creep and plasticity stress exponents differ, by modifying the plasticity correction term in published equations. The plasticity correction term in the newly proposed equations is given in terms of the initial elastic-plastic and steady-state creep stress fields. The predicted C(t) and J(t) results are validated by comparison with systematic elastic-plastic-creep FE results. Good agreement with the FE results is found.
