Micromechanical modelling of twinning-induced plasticity steels

The paper discusses a number of issues related to the development of a micromechanical polycrystalline model for twinning-induced plasticity steels: twinning features that have to be incorporated, identification procedure, description of the work hardening, role of the texture and the role of the interaction law between grains. Monotonous and reverse strain paths are investigated.
