Abstract

Wear of components is a critical factor that influence the product service life, so wear prediction is an important part from the engineering process. Wear simulation can be conducted by mechanistic models and phenomelogical models. The mechanistic models are based on material failure mechanism, while the phenomelogical models often involve calculations using princyples of contact mechanics. The phenomelogical, model which uses a commercial finite element software ANSYS, is presented in this report. Modeling and simulation procedures are proposed with the linear wear law and Euler integration schemes. The Archard’s wear law is used as additional calculation after analysing with Finite Element Method (FEM). The simulation is modeled as a pin-on-disc unlubricated static contact. An elastic Silicone Nitride (SiN4) material is used in the present study. Results of FEM are compared with Hegadekatte results. Wear rate is calculated as a function of sliding distance. The results show that the wear depth increases as the increasing of sliding distance, but the wear rate decreases due to the increasing of contact area.
