Source Excitation

Steady-state periodic excitation at a point of an extended, periodically laminated, elastic composite is considered in antiplane strain. The curves of constant phase are determined in the geometric optics approximation. The associated distribution of group velocity is also calculated.

Transient Case

abstract A simple solution to the problem of the surface displacements on an elastic half-space caused by an underground explosion is presented. The analysis is based on deriving the transient case for a point source from the steady state point source and then proceeding to the case of a finite spherical cavity by means of a retarded potential. Theoretical values of maximum displacement compare favorably with measured values from the underground test shot Rainier, a nuclear explosion of Operation Plumbob.
