This report illustrates the results of a fatigue crack growth analysis performed as part of an international benchmark exercise aimed at qualifying tools to predict the crack growth rate under a cyclic thermal-stress driving force. A thermal, elastic and elastoplastic transient numerical analysis was performed and the results obtained were used to determine the crack propagation. Two different methods were adopted to evaluate the intensity factor range: the weight function method and the J-integral. The content of the present report includes a brief description of both methods and a comparison of the results obtained as far as the stress intensity factor evaluation and the crack growth evolution are concerned.
