Abstract : This report summarizes progress on several theoretical questions concerning contact and fracture phenomena for elastic and viscoelastic material. Specifically, the following topics are discussed: (1) quasi-static sliding contact problems for power-law linearly viscoelastic material; (2) the quasi-static propagation of a crack by a rigid wedge through an infinite power-law linearly viscoelastic body; (3) solution techniques of systems for generalized Abel integral equations with application to simultaneous sets of dual integral equations and interfacial cracks in elastic material; (4) the application of conservation integral techniques to the calculation of energy release rates for elastic interfacial edge cracks; (5) static thermo-elastic interfacial edge cracks; and (6) the dynamic, steady-state fracture of general linearly viscoelastic material.
