Finite Elements computations with release node technique have been carried out in order to simulate the creep crack growth process on the 316 L(N) stainless steel. The numerical C* values computed on a propagating crack are path independent and in agreement with those obtained by simplified methods. Additionally, the master curve was reproduced by computations and seems to be insensitive to the investigated specimen geometry. Furthermore, there is no effect of crack propagation on the stress distribution near the tip of the crack. These results seem to indicate that a creep crack growth prediction via da/dt vs C* curve should be conservative.
