Numerical simulation of nonlinear elastic wave propagation in piecewise homogeneous media

Propagation of Love Waves in a Non-Homogeneous Elastic Media

The propagation of Love waves in a non-homogeneous layer of finite thickness lying over an isotropic semi-infinite medium is discussed in this study. It is assumed that density and rigidity are space dependent and obey the laws  (1+cosz), μ=μ0 (1+cosz), where ‘’is a scaling parameter. The method of variable separation, substitution method for solving the second order partial differen...

Analytical solution of wave propagation in a non-homogeneous orthotropic rotating elastic media

In this paper, the natural frequencies of the radial vibrations of a hollow cylinder and hollow sphere with different boundary conditions under influences of rotation and non-homogeneity have been studied. The radial vibrations of orthotropic material as affected by the angular velocity are investigated on the basis of the linear theory of elasticity. The of elastodynamic equations have been so...

Wavelet Based Simulation of Elastic Wave Propagation

Surface Wave Propagation in Non Homogeneous, General Magneto-Thermo, Visco-Elastic Media

The aim of the present paper is to investigate the surface waves in a non-homogeneous, isotropic, visco-elastic solid medium of nth order including time rate of strain. The theory of generalized surface waves has firstly been developed and then it has been employed to investigate particular cases of waves, viz., Stonely and Rayleigh, Love type. The wave velocity equations have been obtained for...

Numerical simulation of flood wave propagation due to failure of dam watersheds in fluent model

By numerical simulation of the phenomenon of failure of dams and the flow of their flow, it is possible to design more precisely the structures and their location. The purpose of this study was to investigate the wave propagation phenomenon due to the failure of the rocky mortar-watering dam in the Marivan sub-basin of Zarivar in two-dimensional and three-dimensional models using the Fluent mod...
