Wave Propagation in Anisotropic Viscoelasticity

Torsional Surface Wave Propagation in Anisotropic Layer Sandwiched Between Heterogeneous Half-Space

The present paper studies the possibility of propagation of torsional surface waves in an inhomogeneous anisotropic layer lying between two heterogeneous half-spaces (upper and lower half-space). Both the half-spaces are assumed to be under compressive initial stress. The study reveals that under the assumed conditions, a torsional surface wave propagates in the medium. The dispersion relation ...

Notes on Wave Propagation in Anisotropic Elastic Solids

The aim of this document is to summarise the information on elastic material properties, and wave propagation which I have found in my recent reading. The books and papers read are listed at the end of this document, and cited throughout. First, the basic consititutive equations governing elastic solids are presented. Once the concept of elastic properties has been established, our attention tu...

Elastic Wave Propagation and Scattering in Anisotropic Fractured Media

In this thesis, we develop several methods for the delineation and analysis of anisotropic fractures in the subsurface. Our principal goal is to develop methods to use seismic data to infer fracture properties. In turn, we relate this information to the fluid flow properties of anisotropically fractured media. The first problem is to examine media with cracks oriented over a range of directions...

Gaussian-beam propagation in generic anisotropic wave-number profiles.

The propagation characteristics of a scalar Gaussian beam in a homogeneous anisotropic medium are considered. The medium is described by a generic wave-number profile wherein the field is formulated by a Gaussian plane-wave distribution and the propagation is obtained by saddle-point asymptotics to extract the Gaussian beam phenomenology in the anisotropic environment. The resultant field is pa...
