MODAL-ANALYSIS OF SHELL OF REVOLUTION ON ELASTIC-FOUNDATION

Static and dynamic analyses of the shell of revolution on elastic foundation have been analysed by a finite element method based on variational formulation. The general loading consists of laterally distributed forces and ring forces on the meridian and normal to the neutral plane directions and moments. The thermal load is also assumed to act in the meridian direction and the thermal gradient through the thickness. The elastic foundation is assumed to be either in distributed form extending over the entire surface of the element or in ring form applied at a nodal point. The dynamic solution of the resulting finite element equation is obtained using the theoretical modal analysis technique based on mode displacement and mode acceleration methods.
