Displacement aid strain fields due to axially symmetric sources in an elastic half-space in welded contact with another elastic half-space

Abstract

Closed form analytical expressions for the displacement and strain components due to five axially symmetric sources, namely, a vertical force, a vertical dipole, a centre of dilatation, a tensile dislocation on a horizontal fault and a compensated linear vector dipole (CLVD) in an elastic half-space in welded contact with another elastic half-space are obtained. The effect of rigidity contrast of the two half-spaces is investigated numerically. The elastic field due to these axially symmetric point sources in two welded half-spaces is compared with the corresponding field in a half-space and in a homogeneous' unbounded medium.
