The Dynamic Response of an Elastic Half Space with an Overlying Acoustic Fluid.

摘要

A class of dynamic problems involving a semi-infinite elastic solid with an overlying semi-infinite acoustic fluid, subjected at the plane interface to arbitrary normal loading is investigated. A method of solution is proposed which reduces the class of problems under study to that in which the fluid is absent. A specific example is presented for an expanding disk-shaped load including numerical results for the subseismic range.
