Abstract The stone chip resistance performance of automotive coatings has attracted increasing attention in academic and
industrial communities. Even though traditional gravelometer tests can be used to evaluate stone chip resistance
of automotive coatings, such experiment-based methods suffer from poor repeatability and high cost. The main
purpose of this work is to develop a CFD-DEM-wear coupling method to accurately and efficiently simulate
stone chip behavior of automotive coatings in a gravelometer test. To achieve this end, an approach coupling an
unresolved computational fluid dynamics (CFD) method and a discrete element method (DEM) are employed
