Abstract
"Transient and steady state stress-strain hysteresis behavior of several structural metals is analyzed. The study shows that a stress parameter, defined as the ""Yield Range Increment,"" uniquely denotes the various transient phenomena including cyclic hardening, softening, relaxation and creep and the steady state cyclic stress-strain behavior. All transient and steady state hysteresis branches of a given material appear to be identical in shape, after their ""Yield Range Increments"" which are suitable portions of the initial ""elastic"" parts are deleted. A mathematical model incorporating the ""Yield Range Increment"" is proposed. With the determination of the functional relationship between the newly proposed parameter and the several input variables of cyclic loading, this approach should lead to a simple and unified model for describing the cyclic stress-strain response of materials."
