Abstract

In this paper, the influence of plastic material property equations on the initial C(t) and J(t) is investigated by using elastic-plastic-creep FE analysis. For plastic models, three equations with different values around 0.2% yield strength are considered for study. These models are found to have an effect on calculated C(t) values for a short time or redistribution time. In case of J(t), the rate of its change is not affected by the models, whereas J(0) values were affected.
