Modeling of abrasive wear by the meshless smoothed particle hydrodynamics method

摘要

Numerical modeling of surface wear proves to be a very challenging mathematical and numerical problem. Basically nonlinear processes of wear and creation of plastic zones are only the beginning of a large list of factors that have to be incorporated into a numerical model to adequately describe the frictional interaction of solid bodies. This article presents a new approach to numerical modeling of abrasive wear of friction composites under nonstationary friction. It utilizes the meshless smoothed particle hydrodynamics method together with the standard finite element method. The presented numerical examples illustrate both verification of the new approach, as well as results of abrasive wear modeling.
