Abstract

Closed form analytical expressions for the displacement field due to single couples in a layer overlying a half-space using the Fourier Transform Method in term of Galerkin vector are obtained. In engineering, elastic layer represents an elastic plate while in geophysics it represents a lithosphere. This type of coupling of an elastic layer overlying an elastic half-space corresponds to the realistic earth model-lithosphere lying over an asthenoshere. These expressions are true for all Lame’s parameters to remain non-zero and non-infinite. The final results are simple and quite convenient.
