Friction, plasticity and wear are complex issues that engineers must address in the design of mechanical systems. Significant advances in lubrication and advanced materials have allowed for the development of energy efficient and long lasting mechanical devices. However, insights into the physical mechanisms that control parameters such as the friction coefficient, wear rate coefficient, or hardness are lacking, particularly at the atomic scale. Such insights are required for predictive determination of the parameters that control friction, plasticity and wear, which will be critical in the development of the next generation materials and lubricants. We will use novel techniques, such as atomic force microscopy, to examine the mechanical properties of materials at the atomic length-scale.
I am looking for interested and motivated graduate students to begin in winter or spring 2014.
