INFLUENCE OF THE BONDING CONDITIONS ON TH E WAVES EXISTING AT THE BOUNDARY BETWEEN 2 ELASTIC SOLIDS

We study the range of existence of interface waves between two elastic media separated by a bond of thickness small in comparison with the w avelengths. The boundary conditions describing the bond are those intr oduced by Jones, The contact at the interfaces is such that the normal and tangential stresses at the boundary between the two media depend on the bond parameters. The results of Scholte, in the case of two wel ded semi-infinite media are then extended. It is shown that there are zero, one or two interface waves. The physical features of such waves are discussed.
