Gentlemen and ladies,
I have an application for fatigue evaluation where the stress goes above yield. I have briefly surveyed the literature both FEA and fatigue. It appears that I need to specify cyclic stress-strain properties. The materials are AISI 4140 (UTS 150000 psi) and steel UTS 80000 psi. If any one could throw some light on these material properties and how they are to be used in ABAQUS I will be highly obliged.
