11. Summary of the new findings of the thesis

- Linear buckling analysis of stiffened FGM truncated conical shells and sandwich FGM truncated conical shells resting on elastic foundations, subjected to mechanical and thermal loads. The closed-form expression for determining the critical buckling loads are obtained.

- Nonlinear stability analysis of stiffened FGM truncated conical shells resting on elastic foundations, subjected to mechanical and thermo-mechanical loads. The closed-form expressions for determining the critical buckling load and for analyzing the post-buckling load–deflection curves are obtained.

- The nonlinear dynamic response and vibration of FGM truncated conical panel with piezoelectric actuators and stiffened FGM truncated conical shell resting on elastic foundations in thermal environments are analyzed.

- The effects of stiffeners, dimensional parameters, volume fraction index, applied actuator voltage, temperature increment and elastic foundations on buckling, post-buckling behaviors and dynamic response of shell are discussed.
