The effect of initial plasticity on transient creep in plain strain compact tension C(T) specimen under load control is numerically analyzed in this paper. The detailed finite element (FE) analysis was performed by varying the magnitude of the initial step-load, and for general material properties where different plastic and creep stress exponents were systematically varied. Comparisons have been performed between the FE computed C(t) values and available estimation equation. It has been found that the estimation equation provides good agreement with the FE results. |
