Stability of solids with interfaces
Stability, understood as uniqueness of solutions to quasi-static boundary value problems, is investigated for two semi-infinite solids bonded along a planar interface. The interface is characterized by a traction- displacement jump relation, so that dimensional considerations introduce a characteristic length. Stability is addressed in terms of the existence of certain stationary waves. Complex variable methods are exploited to obtain an explicit solution when the interface instability precedes bulk localization.
