Atomistic Simulation of Materials Group

Prof. Yip's research interests in recent years have focused on the theory and simulation of fundamental materials properties and behavior across different length and time scales. He has specialized in developing molecular models to elucidate the atomic-level mechanisms governing such phenomena as melting, elastic instabilities, crack-tip plasticity, solid-state amorphization, and grain-boundary structure and dynamics. His current projects are mostly concerned with mechanical and thermal behavior of structural and functional materials, specifically problems of strength, deformation and toughness of metals and ceramics, dislocation core structure, interactions and mobility, environmental effects of hydrolytic weakening, and studies of electronic and thermal conductivities in nanostructures.
