Abstract

The well known models proposed to qualify the volume of material removal from abrasive particle impact are analytical. They are based on simplified hypotheses and neglect the dynamic response of the structure or of the material. This paper addresses the numerical simulation of the impact of spherical particles on a substrate corresponding to an aluminium alloy sheet (A2024) coated with polyurethane paint (PAC 33). The main mechanism of paint removal is the delamination of the paint. The criterion of delamination is based on the state of stresses at the interface substrate and paint. This criterion has been introduced in the finite element modelling. The numerical results are compared to experimental data.
