The effect of rotation on piezo-thermoelastic medium using different theories
Mohamed I.A. Othman and Ethar A. A. Ahmed
Abstract
The present paper attempts to investigate the propagation of plane waves in generalized piezo-thermoelastic medium under the effect of rotation. The normal mode analysis is used to obtain the expressions for the displacement components, the temperature, the stress and the strain components. Comparisons are made with the results predicted by different theories (Coupled theory, Lord-Schulman, Green-Lindsay) in the absence and presence of rotation.
Key Words
