In this paper, we present a fundamental model of FCC single crystal behaviour at room
temperature: this model includes kinematic work hardening derived from the elementary description
of the collective dislocations density evolution during cyclic loading. This kinematic work
hardening is then coupled with the isotropic work hardening mechanism. Using this original model,
a simulation of a tensile test on a single crystal sample is carried out in the case of an initial crystal
orientation that promotes single glide even at rather large strains. The evolution of resolved shear
stresses on the primary and secondary slip systems are interpreted by means of the interaction
between the evolution of isotropic and kinematic work hardening variables. The evolution of the
model state-variables including applied resolved shear strain, dislocation densities, and critical
shear stresses are represented as functions of the evolution of crystalline orientation during plastic
deformation.
