The present paper describes how to derive and to apply a homogenised constitutive law for composite materials with periodic structure and elastoplastic components. This method is currently restricted to plane problems with monotonic proportional loading. Within such a framework it seems possible to extend the method to components governed by other non-linear constitutive laws satisfying the complementarity condition.

Abstract
The present paper describes how to derive and to apply a homogenised constitutive law for composite materials with periodic structure and elastoplastic components. This method is currently restricted to plane problems with monotonic proportional loading. Within such a framework it seems possible to extend the method to components governed by other non-linear constitutive laws satisfying the complementarity condition.
