2-DIMENSIONAL CONTACT ON AN ANISOTROPIC ELASTIC HALF-SPACE

The two-dimensional contact problem for a semi-infinite anisotropic elastic media is reconsidered here by using the formalism of Eshelby et al. (1953) and Stroh (1958). The approach of analytic function continuation is employed to investigate the half-space contact problem with various mixed boundary conditions applied to the half-space. A key point of the solution procedure suggested in the present paper is its dependence on a general eigenvalue problem involving a Hermitian matrix. This eigenvalue problem is analogous to the one encountered when investigating the behavior of an interface crack (Ting, 1986). As an application, the interaction between a dislocation and a contact strip is solved. The compactness of the results shows their potential for utilization to solve the problem of contact of a damaged anisotropic half-space.
