Abstract

An experimental database on 316L(N) material consisting of creep crack growth tests on CT, CCRB and DENT specimens has been selected for extending the ASTM procedure to produce da/dt vs C* master curve. Finite Elements computations with release node technique have been carried out in order to simulate the crack growth process. The displacement rate partitioning suggested in the ASTM has been verified. Hence, numerical C* values computed on a propagating crack are in agreement with those obtained by simplified methods. Additionally, the master curve seems to be insensitive to the investigated specimen geometry. These results seem to indicate that a creep crack growth prediction via da/dt vs C* curve should be conservative.
