    A micro-macro finite-element model for predicting the cyclic stress-strain response and damage evolution in tool-steel materials is presented. The elasto-plastic constitutive model at the macro-scale ... combines isotropic and kinematic hardening with continuum damage. This permits relatively precise modelling of the critical regions in the tooling systems over a large number of loading cycles. The macroscopic stress-strain fields are coupled with representative volume elements at the micro-level, where interactions between the primary carbides (M6C, MC, V8C7) and the martensitic matrix are evaluated. This provides a detailed insight into the stress-strain fields at the micro-level and reveals the damage mechanisms at the micro-scale. The performance of the model is demonstrated on an industrial example of a tool for the cold precision forming of metals.
