Adhesive wear regimes on rough surfaces and interaction of micro-contacts
Son Pham-Ba, Jean-François Molinari
We develop an analytical model of adhesive wear between two unlubricated rough surfaces, forming micro-contacts under normal load. The model is based on an energy balance and a cra…

An optimized material removal process
Jean-François Molinari, Son Pham-Ba
We conduct boundary element simulations of a contact problem consisting of an elastic medium subject to tangential load. Using a particle swarm optimization algorithm, we find the…

Adhesive wear and interaction of tangentially loaded micro-contacts
Son Pham-Ba, Tobias Brink, Jean-François Molinari
Current engineering wear models are often based on empirical parameters rather than built upon physical considerations. Here, we look for a physical description of adhesive wear at…
