Quasi-adiabatic approximation for thermoelastic surface waves in orthorhombic solids

Effect of Micropolarity, Microstretch and Relaxation times on Rayleigh Surface Waves in Thermoelastic Solids

The present paper is an investigation on the propagation of Rayleigh surface waves in a homogeneous, isotropic, thermally conducting microstretch elastic solid half-space in the context of non classical (generalized) theories of thermoelasticity. The secular equations in closed form and isolated mathematical conditions are derived for Rayleigh wave propagation in such solids. The amplitude rati...

The quasi-adiabatic approximation for coupled thermoelasticity

The equations of coupled thermoelasticity are considered in the case of stationary vibrations. The dimensional and order-of-magnitude analysis of the parameters occurring within these equations prompts the introduction of the new non-dimensionalisation scheme, highlighting the nearly-adiabatic nature of the resulting motions. The departure from the purely adiabatic regime is characterised by a ...

A Mixture Theory for Micropolar Thermoelastic Solids

Reflection and transmission of waves from imperfect boundary between two heat conducting micropolar thermoelastic solids

The problem of reflection and transmission of plane waves at an imperfect boundary between two thermally conducting micropolar elastic solid half spaces with two temperature is investigated. Amplitude ratio of various reflected and transmitted waves are presented when a set of coupled longitudinal wave (LD-wave) and thermal wave (T-wave) and a set of coupled transverse wave and microrotation wa...

Wave Propagation in Mixture of Generalized Thermoelastic Solids Half-Space

This paper concentrates on the reflection of plane waves in the mixture of generalized thermo elastic solid half-space. There exists quasi dilatational waves i.e. qP1, qP2, qT and two rotational waves S1, S2 in a two dimensional model of the solid. The boundary conditions are solved to obtain a system of five non-homogeneous equations for amplitude ratios. These amplitude ratios are found to de...
