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. This latter class has received considerable consideration in the past. A specific example is presented for an expanding disk-shaped load including numerical results for the subseismic range. (Author)
