Propagation of anSH-torque pulse in a three layered solid half-space

Summary The potential functions caused due to anSH-torque pulse from a point source in any of the layers of a three-layered solid half-space have been evaluated in terms of definite integrals, usingCagniard's method. The solution is given as a double infinite series, of which only a finite number of terms contribute to the disturbance at a definite time, and the number of such terms increases with time.
