| Abstract | ||
| This paper presents an investigation of contact surface interface, which is of strong interest for wear applications. The prediction of the wear depth in contact surfaces is thus a challenging task. The effect of the asperities height (0.045, 0.055, 0.065, and 0.07 )mm, the applied forces and the shape of the contact surfaces on the wear depth and contact pressure are investigated by finite element method via ANSYS software. Wear simulation approach based on Archard’s model was proposed, in which ANSYS was used to simulate the progressive accumulation of wear between contact surfaces. Results showed that the wear behavior can be simulated with the series of discrete models and the method proposed can be widely used to predict wear problems for engineering. Two cases are studied, the first one is for rectangular contact surfaces and the other for circle- rectangle contact surfaces with different height of asperities. It was also concluded that the increased of contact’s time caused the wear depth for different asperities increased and vice versa for contact pressure. | ||
