An analytical model is proposed to determine the static response of two perfectly joined homogeneous elastic half-spaces, lower half-space is taken as orthotropic which is in welded contact with upper half-space taken as isotropic. Analytical expressions for stresses caused by a tensile dislocation embedded in the isotropic half-space are obtained. The integral expressions for the stress field are obtained by the usage of Airy stress function. Variations of the stresses with the epicentral distance for various source locations embedded in the upper half-space are discussed with the help of 2-D and 3-D graphics. We have taken the lower half-space as Topaz and Barytes for graphical representation. Numerical computations indicate that the stress field in this model may differ substantially from the stress field when both the half-spaces are isotropic.
