Abstract: Simulation of shot peening on case carburized gear steel demands a material model that include strain rate dependence and martensite transformation. Determining the material parameters is a challenging task due to the mechanical and fracture behaviour of hardened gear steel. A material model and its influence on indent topography during dynamic indentation is presented that will allow reverse modelling of the model parameters using experimental confocal measurements of indent profiles at different velocities.
