Small elastic strains in finite elasto-plastic materials with continuously distributed dislocations

Small elastic strains in finite elasto-plastic materials with continuously distributed dislocations

In this paper we propose a macroscopic model for elastoplastic materials with continuously distributed dislocations, when we restrict to small elastic strains, but the elastic rotations and plastic distorsions remain large. The material is not homogeneous and it behaves like an elastic material elem...
