Abstract
A study has been made of the low-cycle impact fatigue behaviours of low-carbon steel and austenitic stainless steel including cyclic stress-strain behaviour, cyclic hardening and fatigue life. Similarities and dissimilarities in cyclic deformation and fatigue fracture between low-cycle impact fatigue and ordinary low-cycle fatigue of the materials are discussed. This gives evidence for the presence of a considerable strain rate effect in low-cycle fatigue.
