Effect of Rotation on Thermoelastic Medium with Voids and Temperature-Dependent Elastic Moduli under Three Theories
Publication: Journal of Engineering Mechanics
Volume 144, Issue 3
Abstract
This paper is to study the propagation of plane waves in a rotating thermoelastic solid with voids with temperature-dependent elastic moduli. The modulus of elasticity is taken as a linear function of reference temperature. The entire elastic medium is rotated with a uniform angular velocity. The formulation is applied under three theories of generalized thermoelasticity: Lord-Schulman (L-S), Green-Lindsay (G-L), and the coupled theory (CD). The normal mode analysis is used to obtain the exact expressions for the considered variables. Some particular cases are also discussed in the context of the problem. Numerical results for the considered variables are obtained and illustrated graphically. Comparisons are also made with the results predicted by different theories (CD, L-S, G-L) in the absence and presence of rotation and temperature dependent of properties, also with and without voids.
