Effect of Rotation on Thermoelastic Waves in a Non- Homogeneous Infinite Cylinder

In this paper, the problem involving a half-space or an infinite space with a cylindrical or spherical cavity have been subjected to certain boundary conditions. The material is elastic and has an inhomogeneity in the direction perpendicular to the boundary surface for the halfspace problem with a cylindrical or spherical cavity. The system of fundamental equations have been solved by using an implicit finite-difference scheme. A numerical method is used to calculate the temperature, displacement and the components of stresses with time and through the radial of the body. Numerical results have been given and illustrated graphically for each case considered. The results indicate that the effect of rotation and inhomogeneity is very pronounced. Comparison has been made with the results in the absence of rotation.
