Abstract

In this article the analytic and asymptotic properties of the resolvent for elastic waves in a three dimensional domain perturbed from the isotropic half space R^3^~+~ are studied. In this case, the asymptotic expansion of the resolvent at the origin has logarithmic terms. This property is totally different from the case of the whole 3‐dimensional space. The existence of the surface waves like the Rayleigh waves makes this difference. As an application of the asymptotic properties of the resolvent, the rate of the local energy decay estimates for the dynamical equations is obtained. (Β© 2005 WILEY‐VCH Verlag GmbH & Co.

We consider the self-adjoint operator governing the propagation of elastic waves in a perturbed isotropic half-space (perturbation with compact support of a homogeneous isotropic half-space) with a free boundary condition. We propose a method to obtain, numerical values included, a complete set of g

In the present paper, we study reflection of inclined incident plane waves from a free boundary of the half-space in which the material is described by constitutive equations valid for elastic solids with voids. Both the cases of the transverse and longitudinal incident waves are considered, and it
