A review of nonlinear constitutive models for metals [PDF]
Over the past two decades a number of thermomechanical constitutive theories have been proposed for viscoplastic metals. These models are in most cases similar in that they utilize a set of internal state variables which provide locally averaged ...

Integrated research in constitutive modelling at elevated temperatures, part 2 [PDF]
Four current viscoplastic models are compared experimentally with Inconel 718 at 1100 F. A series of tests were performed to create a sufficient data base from which to evaluate material constants.
