Abstract

Scratch test is one of widely used, fast, and effective methods to obtain the critical loads that are related to adhesion properties of coating. The contact situation in a scratch tester is the combination of the hammering and sliding contact. Due to the increasing load of the stylus over an elastic-plastic zone, the surface defect will occur and lead to the creation of some first visible angular cracks in the coating. As a result, this phenomenon will affect to the crack generation and failure mechanism. A three-dimensional finite element model (FEM) for describing the stress-strain behavior under stylus loading was built to get the explain the effect of contact forces for the fracture mechanism.
