Micromechanical local approach to brittle failure in bainite high resolution polycrystals: A short presentation

► Fracture probability of bainite polycrystals is under concern. ► A high-resolution full-field modelling at large deformation is used. ► Crystal constitutive behavior accounts for dislocation density evolution. ► A new micromechanical local approach of fracture is proposed. ► Possibility of multiple microcracks encountering microstructural barriers.
