Experimental and Computational Investigation of Fretting Wear

Fretting is a special wear process that occurs at the contact area between two materials under load and subject to minute relative motion by vibration or some other force. It is different because microscopic contact parameters are more influential than the actual input parameters like sliding distance or gross amplitude. The purpose of this research is to experimentally investigate the fretting wear phenomenon, evaluate wear coefficients and generate wear maps for different sets of materials. A damage mechanics model to predict wear rates has been developed. A fracture mechanics model to predict wear rates due to subsurface crack propagation is also investigated. Furthermore, effect of surface roughness parameters on wear is also modeled using a novel, computationally efficient model. Effect of plastic deformation, role of microstructure in fatigue crack propagation and experimental investigation of third body particles are currently under investigation.
