Generation of SH-wave in a medium of welded two-quarter spaces with a uniform layer on one quarter space.

This paper examines the generation of elastic SH-waves in a medium of two-quarter spaces in welded contact with a layer of uniform thickness overlying one of the quarter spaces. Impulsive surface tractions on the surface generate the waves. Transform methods are employed to obtain the functional integral equation in the general case. Approximations are made when a layer overlies a halfspace to obtain the solution. The displacement at the surface of the layer is obtained as a series of definite integrals representing the different pulses reflected at the interface between the layer and the halfspace.
