Résumé :

This paper addresses the issue of incorporating mech. twinning in a crystal plasticity model originally designed for dislocation slip only. Iso-deformation in the twin and in the parent grain have been considered. Different hypotheses are formulated about the interaction of adjacent grains: (i) uniform deformation (Taylor FC); (ii) Lamel model and (iii) ALAMEL model. One evaluates the effect of such hypotheses on the prediction of hardening, vol. fraction of twins and texture evolution. Then, model predictions are compared to exptl. measurements of the rolling texture on a Fe-Mn-C alloys in which the occurrence of mech. twinning is controlled both by the chem. compn. and the working temp.
