Coupled thermoelasticity of shells of revolution: Effect of normal stress and coupling

The coupled thermoelasticity of shells of revolution, based on second-order shell theory, is considered, and the governing equations including normal stress and strain as well as the transverse shear and rotary inertia are co nsidered. The coupled energy equation based on the assumption of Lord and S hulman (Lord, H. W., and Shulman, Y., "A Generalized Dynamical Theory of Th ermoelasticity,'' Journal of Mechanics and Physics of Solids, Vol. 15, No. 5, 1967, pp. 299-309) is further considered, and the total system of equati ons is served by means of Galerkin finite element method. it is concluded t hat the inclusion of normal stress in the coupled equation is significant a nd for thin shells can result in a noticeable difference in shelf response compared to unassumed conditions.
