Abstract

This paper describes a study of fatigue closure of part-through cracks in notched, 5 mm thick, Al---Cu alloy sheet specimens. The study used a specially designed electron fractography technique which enables accurate assessment of closure and its development wit crack extension, as well as its variation across the crack front. The effect of prior overloads on notch root crack closure was also investigated.
