Multi-mechanism modeling of proportional and non-proportional ratchetting of stainless steel 304

Abstract : This work is devoted to a survey of the multi-mechanism (MM) models proposed in literature during the last two decades. This MM approach is a possible alternative to the wide-spread Chaboche’s model when modeling complex material behavior. Here, the description of the cyclic behavior under complex loading histories is in the focus. The capabilities of two recent versions of the MM models are demonstrated through the simulation of cyclic proportional and non-proportional loading paths under stress or the combination of stress–strain control. The reliability of the two MM models is investigated through the study of the mechanical behavior of a 304 stainless steel (304 SS) at room temperature. Beside the assessment of the stress–strain overall behavior, the local contribution of stress and strains at each mechanism level is discussed.
