The purpose of this paper is to study the two dimensional deformation in a thermoelastic micropolar solid with cubic symmetry. A mechanical force is applied along the interface of a thermoelastic micropolar solid with cubic symmetry (Medium I) and a thermoelastic solid with microtemperatures (Medium II). The normal mode analysis has been applied to obtain the exact expressions for components of normal displacement, temperature distribution, normal force stress and tangential coupled stress for a thermoelastic micropolar solid with cubic symmetry. The effects of anisotropy, micropolarity and thermoelasticity on the above components have been depicted graphically.

The present paper concentrates at studying the analysis of wave motion in a homogenous isotropic micropolar plate possessing cubic symmetry. The upper and lower surfaces of the plate are subjected to stress free conditions. The frequency equations for symmetric and skewsymmetric wave modes of propagation are derived. The amplitudes of displacement components and microrotation are also computed and presented graphically during the symmetric and skewsymmetric motion of the plate. Finally, in order to illustrate and verify the analytical developments, numerical solution of frequency equation corresponding to stress free micropolar cubic crystal plate is carried out for magnesium crystal material and represented graphically. The results of phase velocity, displacements and microrotation have been compared for micropolar cubic crystal plate and micropolar elastic plate and illustrated graphically.

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 stress, tangential couple stress, temperature distribution and pressure an acoustic fluid have been depicted graphically for different load velocities. Some special cases are also deduced.

The analytic expressions for the displacements, microrotation, stresses and temperature distribution on the free surface of micropolar thermoelastic medium possessing cubic symmetry as a result of inclined load have been obtained. The inclined load is assumed to be a linear combination of a normal load and a tangential load. The Laplace and Fourier transforms have been employed to solve the problem. A special case of moving inclined load has been deduced by making the appropriate changes. The variations of the displacements, microrotation, stresses and temperature distribution with the horizontal distance have been shown graphically for both the problems.
