Experiments with preloaded notched members of 2024-T3 aluminum alloy have shown that preloads in a wide range, even including those which create overall yielding, increase the fatigue lives of the members. Evidence suggests that the extended fatigue life is primarily due to the residual compressive

Al&net-Fatigue life predictions for notched members are made using local strain and elastic-plastic fracture mechanics concepts. Crack growth from notches is characterized by J-integral estimates made for short and long cracks. The local notch strain field is determined by notch geometry, applied st
