•Salt rock fatigue induced by cyclic loading is modeled by upscaling grain viscoplastic deformation and breakage.•A failure criterion is introduced in a self-consistent homogenization scheme initially proposed for visco-plastic materials.•The model captures strain hardening, creep recovery, damage a...
