Transient wave propagation in an elastic layered medium.

Wave Propagation in Micropolar Thermoelastic Diffusion Medium

The present investigation is concerned with the reflection of plane waves from a free surface of a micropolar thermoelastic diffusion half space in the context of coupled theory of thermoelastic diffusion. The amplitude ratios of various reflected waves are obtained in a closed form. The dependence of these amplitude ratios with an angle of propagation as well as other material parameter are sh...

Wave Propagation in Generalized Thermodiffusion Elastic Medium with Impedence Boundary Condition

In the present investigation, we study the reflection of plane waves, that is, Longitudinal displacement wave(P-Wave), Thermal wave(T-Wave) and Mass Diffusive wave(MD-Wave) in thermodiffusion elastic-half medium which is subjected to impedence boundary condition in context of one relaxatioon time theory given by Lord and Shulman theory (L-S) and the Coupled theory (C-T) of thermoelasticity. The...

Parallelized Transient Elastic Wave Propagation in Orthotropic Structures

We discuss the parallelization of a Velocity-Stress FDTD (VS-FDTD) code for the simulation of the propagation of mechanical waves in three-dimensional microstructures. The C++ code has been parallelized using MPI making extensive use of the Blitz++ library for local computation. We present numerical results for pyramid shaped domains, representing the tip of a focusing lens, that we have obtain...

Influence of Heterogeneity on Rayleigh Wave Propagation in an Incompressible Medium Bonded Between Two Half-Spaces

The present investigation deals with the propagation of Rayleigh wave in an incompressible medium bonded between two half-spaces. Variation in elastic parameters of the layer is taken linear form. The solution for layer and half-space are obtained analytically. Frequency equation for Rayleigh waves has been obtained. It is observed that the heterogeneity and width of the incompressible medium h...
