The Interface of a Bimaterial Crossed by a Line Force

The 3D deformation of a bimaterial subjected to a dislocation composed of two straight semi-infinite arms is known when the two arms are placed on each side of the interface. The resolution is possible taking into account an anisotropic elasticity for both media, thanks to the use of the concept of dislocation/force proposed by Belov (1992). By generalizing the analysis of this author, it is possible to solve a similar problem having an angular geometry, but which concerns a line force crossing the interface. For isotropic media, the solution can be formulated explicitly when the two arms are continuous and perpendicular to the interface. A few numerical applications illustrate the calculations for environments with different elastic properties and for different orientations of the two arms.
