Single and intermittently repeated tensile overloads were applied to precracked compact type specimens using austenitic manganese steel which strain hardens under cyclic loading. Delayed crack retardation following overloading was observed macroscopically and verified microscopically with a scanning electron microscope. Crack growth during delayed retardation varied up to 0.10 in. or up to about 30 percent of the overload reversed plane stress plastic zone size and involved up to
fatigue (materials), fracture properties, stresses, strain hardening, overloads, crack propagation, striations, cracks, residual stress, plastic deformation, retarding, steels, mechanical properties
