This course focuses on mechanics aspects of adhesion and fracture of solids. The topics are intimately related, as fracture involves decohesion. Topics include forces of interaction between surfaces of solids, perfect versus imperfect adhesion, aspects of contact mechanics, linear analysis of cracks in elastic materials, non-linear analysis of cracks in elastic-plastic materials, J-integral methods, phenomenological theories, crack growth and heeling, and stability. Micro-mechanical models of fracture are analyzed using non-linear elasticity and energy methods. Applications to various material systems and processes, including structural materials, layered materials, friction and wear.
