Conclusion
In this work, the anisotropic work-hardening behaviour under strain-path changes at moderately large strains has been modelled by using an internal-variable approach. Several intragranular deformation mechanisms, such as the formation of persistent dislocation structures under monotonic deformation, depolarization of preformed microstructure under stress reversal, and the interaction between preformed microstructure and microbands, have been taken into account in choosing the internal variables and their evolution equations. The model has been identified and validated for a mild steel and the aluminium alloy Al 3004 (in both the H19 and recrystallized states).
