ABSTRACT: Strain hardening in austenitic stainless steels is modeled according to an internal state variable
constitutive model. Derivation of model constants from published stress-strain curves over a
range of test temperatures and strain rates is reviewed. Model constants for this material system
published previously are revised to make them more consistent with model constants in other
material systems.
