Elastic wave simulation based on modal excitation in 3D medium

Parallel numerical simulation of wave propagation in 3D elastic medium with application of the Laguerre transform

In this paper, we apply an approach for numerical simulation of elastic waves in heterogeneous medium, based on the implementation of integral Laguerre transform with subsequent domain decomposition. Following the Laguerre transform, we obtain a system with strictly negative definite elliptic operator, which doesn’t depend on separation parameter. Therefore, parallel calculations can be organiz...

Wavelet Based Simulation of Elastic Wave Propagation

Elastic Wave Propagation Simulation System Based On Parallel Processing Architecture

The authors developed numerical methods based on Local Interaction Simulation Approach (LISA) and Elastodynamic Finite Integration Technique (EFIT) for simulation of elastic wave propagation in structures. The methods have been implemented in the simulation framework using parallel processing architecture Computer Unified Device Architecture (CUDA) offered by graphical processing units (GPUs). ...

Traveling Wave Solutions of 3D Fractionalized MHD Newtonian Fluid in Porous Medium with Heat Transfer

In the present paper, we get exact solutions of Magnetohydrodynamic (MHD) of the fractionalized three-dimensional flow of Newtonian fluid with porous and heat transfer through the traveling wave parameter. The governing equations are produced dependent on established Navier-stokes equations which can be diminished to ordinary differential equation by wave parameter ξ=ax+by+nz+Utα/Γ(α...

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...
