Abstract
In this paper, the problem involving rotating half-space or rotating an infinite space with cylindrical or spherical cavity. The material is elastic and has an inhomogeneity in the direction r-axis. The fundamental equations are solved by using finite-difference method. 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 are given and illustrated graphically for each case considered. The results indicate that the effect of rotation and non-homogeneity is very
pronounced. Comparison made with the results in the absence of rotation and non-homogeneity media.
