Turbo generators for nuclear plants are mostly equipped with hydrogen cooling systems. Current practice of characterizing the growth of fatigue cracks on the basis of fracture mechanics primarily relies on fatigue tests for long cracks which are typi

Fatigue lifetime assessment is essential in the design of structures. Under-estimated predictions may result in unnecessary in-service inspections. Conversely, over-estimated predictions may have serious consequences on the integrity of structures. I

The plasticity-induced crack closure shielding effect for long and short through-thickness cracks is studied in a 304L steel. A main objective is to uncouple the effect of the wake length from that of the wake history. The experimental results are pr
