Well Posedness of Constitutive Equations of the Kinematical Hardening Type
The purpose of the first part of these Lectures is to characterize the class of elastic-plastic materials starting from the more general class of the materials with elastic range and introducing a small number of ad hoc assumptions. This is done in the general framework of NOLL’s new theory of simple materials  After some preliminary work intended to re-define in this new context the class of materials with elastic range, a supplementary assumption on the nature of the inelastic behaviour defines a subclass of materials with elastic range of the rate type, which exhibits a number of mate rial properties considered as typical of elastic-plastic materials.
