The present study deals with the propagation of waves in a transversely isotropic micropolar generalized thermoelastic material possessing temperature dependent elastic properties. After developing the solution for LS, GL and CT theory, the phase velocities and attenuation quality factor have been obtained. The expressions for amplitudes of stresses, displacements, microratation and temperature distribution...
The present investigation deals with the propagation of circular crested Lamb waves in a homogeneous micropolar transversely isotropic medium. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and microrotation are computed numerically for magnesium as a material and the dispersion curves, amplitudes...
The article is presented to enhance our knowledge about the propagation of Lamb waves in the layer of a viscoelastic transversely isotropic medium in the context of thermoelasticity with GN theory of type-II and III. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and temperature distribution were...
Rayleigh waves in a half-space exhibiting microplar transversely isotropic generalized thermoelastic properties based on the Lord-Shulman (L-S), Green and Lindsay (G-L) and Coupled thermoelasticty (C-T) theories are discussed. The phase velocity and attenuation coefficient in the previous three different theories have been obtained. A comparison is carried out of the phase velocity, attenuation coefficient...
The present investigation deals with the propagation of waves in a micropolar transversely isotropic half space with an overlying inviscid fluid layer. Effects of fluid loading and anisotropy on the phase velocity, attenuation coefficient, specific loss and relative frequency shift. Finally, a numerical solution was carried out for aluminium epoxy material and the computer simulated results for the...
Propagation of waves in a micropolar monoclinic medium possessing hermoelastic properties based on the Lord- Shulman (L-S),Green and Lindsay (G-L) and Coupled thermoelasticty (C-T) theories is discussed. The investigation is divided into two sections, viz., plane strain and anti-plane strain problem. After developing the solution, the phase velocities and attenuation quality factor have been derived...
The present investigation deals with the reflection of plane periodic waves incident at the surface of a homogeneous initially stressed transversely isotropic fibrereinforced thermoelastic medium. The wave equations are solved by imposing proper conditions on displacements, stresses and temperature distribution. Numerically simulated results have been depicted graphically for different angles of incidence...

The article reports on a methodology to synthesize the response of an inhomogeneous thermoelastic half space subjected to an instantaneous mechanical and thermal source. The Fourier transform is used to solve the problem. The transformed components of normal stress, tangential stress, displacement and temperature distribution are obtained. The effect of inhomogenity is depicted graphically on the...
The problem of dynamic deformation of a fibre-reinforced elastic layer overlying a fibre-reinforced, transversely isotropic, generalized thermoelastic halfspace subjected to various sources has been studied. The closed form solutions for stresses and temperature distribution are obtained by applying thwe Laplace transform on time and Fourier transform on space variables. As an application of the approach...
The steady state response at an interface of an acoustic fluid and a micropolar thermoelastic medium possessing cubic symmetry due to a moving load has been studied. The thermoelastic theory formulated by Chandrashekharia and Tazu (1998) has been used. Fourier transforms have been inverted by using a numerical inversion technique. Effect of anisotropy on the components of normal strain, normal force...
