摘要
A series of experimental investigations concerning the residual stress fields at cold-expanded fastener holes and of the behavior of Fatigue cracks at such holes has been conducted. These studies have included measurement of the initial, cold-work-induced residual stress fields at both uncracked and cracked holes and the performance of both constant amplitude and spectrum fatigue crack growth tests.
