This paper suggests a new method to take into account the kinematic hardening in constitutive behaviour of metallic face centred cubic single crystal. The keystone of this model is that kinematic effect arises from a description of the crystal dislocation microstructure based on a heterogeneous distribution of slip strength. In this paper, these concepts are applied to crystalline plasticity models. In particular, simulations of monotonous tensile test and cyclic loading are analysed to show that implementation of the proposed concepts, without any additional complexity, gives the current model a wide range of applications from small cycled strains to large monotonous ones.
