Search for: [Abstract = "The aim of this study is to determine the elastoplastic properties of metallic polycrystals at large strains using the statistical methods developed by E. Kr ner \[e.g.\: Graded and perfect disorder in random medium elasticity. J. Eng. Mech. Div., ASCE 106, 889\-914 \(1980\)\]. The large number of microfields describing the internal structure evolution is taken into account. The evolution laws for these parameters are recalled or proposed. A few numerical results are finally presented which illustrate the evolution of the internal structure. Special attention is focussed on internal stresses and on stored energy linked with these second\-order residual stresses and their influence on the overall behaviour of the polycrystal."]
