Finite Element Simulation of Abrasive Wear and Study of Wear Resistance of Material
Abstract:
This paper presented the abrasive wear process of a particle pressing into the material and sliding on the surface simulated by finite element method to reveal wear characteristics and effect factors. The contact stress and surface deformation of material were indicated and material wear resistance was studied, it was found that the stress and the deformation of subsurface not only depends on mechanical properties of material and original surface shape, but also on deformed surface profile due to sliding. In order to prove the effects of material yield stress and deformation harden property on surface deformation and abrasion resistance property, the abrasive wear of three kinds of carbon steel were taken for examples, the simulation results were presented that the larger yield stress of carbon steel, the less surface deformation and the better abrasion resistance property when a particle sliding on the surface. The simulation results also shown that the deformation harden of carbon steel could reduce surface deformation, but couldnt always improve abrasion resistance property.
