Nonlinear long wave models for imperfectly bonded layered waveguides

A composite lattice model is proposed to describe nonlinear waves in a two-layered waveguide with adhesive bonding. We begin by considering waves in an anharmonic chain of oscillating dipoles and show that the corresponding asymptotic long wave model for longitudinal waves coincides with the Boussinesq-type equation, earlier derived for a macroscopic waveguide using the nonlinear elasticity app...

Experimental Studies of Wave Transmission through Single Perforated Sheets and Upright Perforated Wave Filters

Transmission of longitudinal wave through micro-porous elastic solid interface

An investigation of reflection and transmission phenomena of plane longitudinal wave from a plane interface between two distinct micropolar porous elastic solid half-spaces in welded contact has been made. Using the method of potentials, the appropriate boundary conditions at the interface are solved to obtain the amplitudes of various reflected and transmitted waves. It has been noticed that t...

Reflection and Transmission of Longitudinal Wave at Micropolar Viscoelastic Solid/Fluid Saturated Incompressible Porous Solid Interface

In this paper, the reflection and refraction of longitudinal wave from a plane surface separating a micropolar viscoelastic solid half space and a fluid saturated incompressible half space is studied. A longitudinal wave (P-wave) impinges obliquely at the interface. Amplitude ratios for various reflected and transmitted waves have been obtained. Then these amplitude ratios have been computed nu...

Impact of Initial Stress on Reflection and Transmission of SV-Wave between Two Orthotropic Thermoelastic Half-Spaces

Reflection and transmission of plane waves between two initially stressed thermoelastic half-spaces with orthotropic type of anisotropy is studied. Incidence of a SV-type wave from the lower half-space is considered and the amplitude ratios of the reflected and transmitted SV-wave, P-wave and thermal wave are obtained by using appropriate boundary conditions. Numerical computation for a particu...
