A Survey of Current Temperature Dependent Elastic-Plastic-Creep Constitutive Laws for Applicability to Finite Element Computer Codes.

Abstract

The volume of the research effort currently under way to characterize the constitution of thermoelastic-plastic-creep materials is ample evidence of its importance. Although significant work has been done to obtain working constitutive models, in many cases the theory has not been cast with the remaining field equations into a working continuum model. In this paper, the author will consider models from classical plasticity and nonlinear viscoelasticity theory for applicability to the conservation of momentum. Based on physical accuracy as well as computational efficiency the author will assess the feasibilty of further development of each model. (Author)
