Abstract
It has been experimentally demonstrated that interaction of residual stresses in the zones of stress concentrators and fatigue cracks induced by cyclic loading with stresses induced by strengthening treatment results in the formation of a residual stress field that differs essentially from the initial one.
Keywords: residual stresses, stress concentration, fatigue resistance, fatigue crack, strengthening treatment
