On Identification of the Wear Law of Viscoelastic Materials from the Results of Standard Wear Testing

The paper describes the theoretical model of contact between a spherical indentor and a rotating disc made of a viscoelastic material. Numerical analysis of the effect of the load and velocity conditions on the disc wear rate is carried out. It is shown that it is important to select an adequate contact model which considers the rheological behavior of the disc material when identifying the wear law from the corresponding test results.
