Abstract

A general theory for structural models governed by multivalued relations is presented. It is based on the definition of a generalized elastic model and provides an unified framework for many different models usually adopted in the literature. The main properties of this model are investigated, existence and uniqueness conditions are discussed and the relevant variational prin- ciples are derived. An application to elasto-plasticity enlights the unifying features of the theory. INTRODUCTION An accurate analysis of most of the results and solution procedures developed in the literature for different structural models which, at a first glance, are characteristic of a particular context, reveals that they are in fact derived by more general properties which allow a treatment in an unified framework. As an example, elasto-static problems can be addressed b
