Crack Initiation, Propagation, and Arrest in 316L Model Pipe Components under Thermal Fatigue
A combined experimental and numerical investigation has been conducted on cylindrical components of 316L stainless steel subjected to cyclic thermal shocks of varying intensity. Under the applied loading, a network of cracks initiates at the inner surface; some of these propagate further through the wall thickness. The number of cycles to crack initiation is estimated from surface replicas taken during intermittent stops, whereas the crack depth of fatigue cracks is measured using an ultrasound technique. Predictions of the crack initiation life are in good agreement with the test results.
