Cutting edges of a bucket loader serve under extremely demanding conditions in mining due to high stress abrasion and hard particle impacts exhibited by the steel materials. One common material choice for the hostile wear environment is martensitic steel that has high strength and reasonable ductility. To investigate the material performance, we employ a multi-scale approach. A macroscopic finite element model is used to study loading conditions taking place at the cutting edge in a more realistic manner by thrusting a cutting edge into a rock pile. The loading history is extracted from the numerous rock-steel contacts to subject loading to the microstructure scale model that is generated in respect to the actual microstructure. A crystal plasticity framework is used to describe the deformation at microscale leading to damage of the material which is the source of the wear phenomena and an indicator of the material performance.
