abstract
in this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (fsdt). these equations are solved by using multi-layer method (mlm). the model has been verified with the results of finite element method (fem). finally, some numerical results are presented to study the effects of thermal and mechanical loading, geometry parameters of truncated conical shell.
