Abstract

Biaxial experiments on the austenitic stainless steel AISI 316H have been performed at strain rates ranging between 0.01 and 10/s, using a specially developed cruciform specimen and two novel sets of loading equipment. The ability of the specimen to identify directly the viscoplastic material properties has been demonstrated by experiment as well as by numerical calculation. Dynamic yield surfaces were detected by traditional methods and also by means of singular temperature points. Constitutive models were calibrated by means of multiaxial experimental results for strain rates of the order 0.001/s (electromechanical testing machine) and 10/s (hydropneumatic testing machine).
