ELASTIC FIELDS DUE TO DEFECTS IN TRANSVERSELY ISOTROPIC BIMATERIALS

A method for obtaining the analytic solution of the elastic fields due to defects such as inclusions, dislocations, disclinations, and point defects in transversely isotropic bimaterials is presented. The bimat erial consists of two semi-infinite transversely isotropic solids eith er perfectly bonded together or in frictionless contact with each othe r at a planar interface which is parallel to the plane of isotropy of both solids. The elastic solution is expressed in terms of the hexagon al stress vectors for the double force and the double force with momen t. Closed form solutions for inclusions with pure dilatational eigenst rain, straight dislocation and disclination lines, circular dislocatio n loops, and point defects are presented.
