Abstract Evaluation of the fatigue behavior of stamped parts requires a knowledge of the effects of large prestrains on fatigue. This paper reports the results of a test program carried out to investigate the effect of tensile and rolling prestrains on the fatigue strength of SAE 1010 and Maxiform 50 steels. Large rolling-induced prestrains were shown to cause a significant increase, while large tensile prestrains (up to 0.9 times the true fracture strain of the steel) caused a moderate increase in the long-life fatigue properties of these steels. Still larger tensile prestrains (0.95 times the true fracture strain) caused the fatigue strength to reduce to its initial value.
