Transmission of Elastic Waves through a Homogeneous Layer Sandwiched in 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...

Propagation of electromagnetic waves in non- homogeneous media

We consider electromagnetic waves propagating in a periodic medium characterized by two small scales. We perform the corresponding homogenization process, relying on the modelling by Maxwell’s partial differential equations. Key wordsMaxwell’s equations, Homogenization, two-scale convergence, oscillating test functions. (MSC)-2000: 35Q60, 35B27 [email protected] hassan.taha@labo...

Instability Analysis of Miscible Displacements in Homogeneous Porous Media

Experimental Investigation of the Permeability and Inertial Effect on Fluid Flow through Homogeneous Porous Media

The value of the permeability in fluid flow through porous media is important for process investigation. In low Reynolds number, the classic Darcy’s law is suitable for simulation of fluid flow. In this paper, an experimental study for evaluation of preformed fiber permeability has been done. Also, the deviations from the classical Darcy law by experimental and numerical simulation of the N...

Fracture Analysis of a FGM Strip Containing Multiple Interface Cracks Sandwiched between Two Homogeneous Layers

A FGM layer sandwiched between two isotropic layers weakened by several interface cracks under antiplane loading is studied. This paper examines the modelling of cracks by distribution of strain nuclei along crack lines. In this investigation, the Volterra-type screw dislocation employed between FGM and an elastic layer. To solve the dislocation problem, the complex Fourier transform is applied...
