Resumen de Synthesis of the elastoviscoplastic behavior and modelization of an austenitic stainless steel over a large temperature range, under uniaxial and biaxial loadings, Part II: Phenomenological modelization

P. Delobelle

• In part I of this paper (Delobelle [1993]), a fairly complete set of mechanical properties of an austenitic stainless steel has been reported that covers a vast temperature range. Different physical mechanisms of the deformation have been identified. In this part, a phenomenological formulation is proposed for each of the mechanisms in question. When integrated in modular form into the context of a unified viscoplastic model, formulated for an extended temperature range, it allows the description of a large variety of behaviors observed between 20° and 700°C.
