Abstract Scope In this study, a computational approach is proposed to simulate a thermo-mechanical process consisting of cold rolling followed by annealing. From microstructural information of as-received hot-rolled sheet, crystal plasticity finite element model incorporating dislocation density based constitutive laws is accounted for to calculate the deformation and stress development during the cold rolling process, while a phase field model can reproduce microstructure evolution of the cold-rolled sheet during an annealing process. Particularly, the current modeling framework accounts for the shear band formation to evaluate the effect of the shear band on texture evolution during both rolling and annealing. Predicted microstructure and its effect on mechanical behavior are discussed by the proposed virtual thermo-mechanical process under various process factors. Finally, the calculated mechanical responses and microstructures are validated by comparing them with experimental data to estimate the accuracy of the model.
