A dynamic two-dimensional problem has been considered to investigate the disturbance due to mechanical and thermal sources in a homogeneous thermal conducting poroelastic medium. Laplace and Fourier transform technique is used to solve the problem. The application of the concentrated and distributed sources are taken to illustrate the utility of the approach. The transformed components of displacement,...
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 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...
The two-dimensional deformation of homogeneous, thermally conducting monoclinic material as a result of inclined line load is investigated by applying the fourier transform. the inclined load is assumed to be a linear combination of a normal load and a tangential load. the displacements, stresses and temperature distribution so obtained in the physical domain are computed numerically and illustrated...
The disturbance due to a time harmonic mechanical or thermal source in a homogeneous, anisotropic, generalized thermoviscoelastic half-space is investigated by applying the Fourier transform. The integral transform has been inverted by using a numerical technique to the components of displacements, stresses, and temperature distribution in the physical domain for the Lord-Shulman (L-S) theory, Green-Lindsay...
The steady-state response of a micropolar cubic crystal due to a moving load has been studied. The eigen value approach using the Fourier transform has been employed and the transform has been inverted by using a numerical technique. The displacement and stress components in the physical domain are obtained numerically. The results of displacement and stresses have been compared for the micropolar...
The voids effect of loads which are moving at a constant velocity along one of the coordinate axis in a generalized thermoelastic half-space is studied. The analytical expressions of the displacements, stresses, temperature distribution and change in the volume fraction field for two different theories, i.e., Lord-Shulman (L-S), Green-Lindsay (G-L) are obtained by the use of the Fourier transform...
The analytic expressions for the displacements, microrotation, stresses and volume fraction field on the free surface of a micropolar elastic half-space with voids as a result of moving an inclined load have been obtained. The inclined load is assumed to be a linear combination of a normal load and a tangential load. The problem has been solved by employing the Eigen-value approach after using the...
The steady state response at viscous fluid/micropolar elastic solid interface to a moving point load has been studied for subsonic, supersonic and transonic load velocities. The Fourier transform has been used to solve the problem. The displacement, microrotation and stress components for a micropolar elastic solid so obtained in the physical domain are computed numerically by using the numerical...
The steady state response of a micropolar elastic solid with an overlying semi-infinite thermal conducting fluid subjected at the plane interface to a moving point load is determined. The analytic expressions of displacement components, force stress, couple stress and temperature distribution are obtained in the physical domain for Lord-Shulman (L-S), Green-Lindsay (G-L), coupled theory (C-T) and...
The disturbance due to a time harmonic mechanical, horizontal or vertical and thermal source in a homogeneous, thermally conducting cubic crystal, elastic half-plane is investigated by applying the Fourier transform. The displacements, stresses and temperature distribution so obtained in the physical domain are computed numerically and illustrated graphically. The numerical results of these quantities...
