... based on Hertz's theory. The calculation results were compared with the simulation results, showing a low error level (0.70–4.63%), depending on the analyzed parameter, i.e., Hertzian stress or maximum shear stress. The numerical results confirm the significant dependence of the erosion resistance...

... stress quantities are critical and larger grains where the stresses are less critical. This paper presents a 3D topologically equivalent model of granular material microstructures, which can be used to investigate subsurface Hertzian stress fields that arise in RCF. The microstructure topology model...
