      The P waves are an elastic wave (E wave) and a thermal wave (T wave) having similar characteristics to the fast and slow P waves of poroelasticity (e.g. Carcione ). Indeed, Carcione et al.

An integral equation is used to derive formal expressions for the scattering of a plane wave from a single homogeneous flaw embedded in an isotropic elastic medium. The distribution of scattered energy due to the interaction of spherical elastic dilatational waves with a spherical cavity is found to differ from that due to plane waves for long wavelengths even when the radius of curvature is much larger than the cavity by: 1.

Propagation of a plane wave. A plane wave is a solution of the propagation equation that propagates in an direction orthogonal to a plane, with normal k^, and its electric field is E→rt=E→0ejωct−kck^.r, with E→0 such that E→0.k^=0.

Contrary to the previous case, the wave presents constant amplitude and phase on a plane orthogonal to k^. In this article, propagation of plane waves in an isotropic modified couple stress generalized thermoelastic with mass diffusion solid has been investigated. The phase velocity, attenuation coefficient, specific loss and penetration depth of plane waves are computed and presented graphically for different values of frequency.

Introduction. In this paper we study a class of travelling shear waves in incom-pressible nonlinearly viscoelastic media with three goals: i) to present exact solutions for a family of properly invariant equations of non-linear viscoelasticity, ii) to study the roles'of nonlinear elastic response and nonlinear viscous response in determining.

Dynamic stress and displacement in an elastic Jiang et al. [19] studied the scattering of plane waves by a cylindrical cavity with lining in a poroelastic half-space by using the complex variable functionmethod. In this study, dynamic response of an elastic half-space with a cylindrical cavity of circular cross-section is Cos ¸kun et.Since the strains are small, all the governing equations for linear elastic materials can be linearized, and are therefore relatively easy to solve.

Linear elasticity theory is thus the best known and most widely used branch of solid mechanics. 4.
