Love waves and primary stress

DEPARTMENT OF MATHEMATICS UNIVERSITY OF LEICESTER, LEICESTER, England

Abstract

The influence of primary stress upon the propagation of Love waves in a welded layer and half-space is examined by means of the theory of nonlinear elasticity. It is shown that the dispersion equation for this case can be cast into the form appropriate in the absence of stress, provided certain rescaling substitutions are employed. The possibility that additional instabilities are introduced through the combined action of primary stress and surface and interfacial continuity requirements is discounted.
