elastic analysis of rotating thick cylindrical shells under linear variable pressure and bi-directional temperature loading

In this paper, a bi-directional thermoelastic analysis of a rotating thick cylindrical shells subjected to mechanical loading is presented. the formulation is based on the first-order shear deformation theory (fsdt), which accounts for transverse shear. the governing equations, derived using the minimum total potential energy principle, are solved using the multi-layered method (mlm). solving this set of equations, applying boundary conditions and continuity conditions between the layers, yields displacements and stresses. finally, the displacements and stresses along the radius and length are plotted, and their distributions are compared with solutions obtained using the finite-element method (fem). to the best of the researchers’ knowledge, in the literature, there is no study carried out bi-directional thermoelastic analysis of clamped-clamped rotating thick shells under linear variable pressure in the longitudinal direction.
