Description
Summary:Based on the classical theory cylindrical shell, the object of the present investigation is to give analytical solutions to illustrate the effect of the magneto-electro-elastic (MEE) material layer properties on the nonlinear vibration of smart sandwich cylindrical shell supported by elastic foundations and subjected to the combination of external pressure, thermal, electric and magnetic loads. This work takes advantage of the sandwich shell configuration with three layers: two MEE face sheets and a carbon nanotube reinforced nano-composite core to analyze the vibration problem. In each MEE face sheet, the volume fraction of BaTiO 3 – CoFe 2 O 4 is chosen to be 0.5, and for the core layer, three types of CNT distribution such as FG-O, FG-V and FG-X are considered. The reliability of present results is evaluated by comparing with the previous results based on a different approach. In addition, the special type of the cylindrical shell, elliptical cylindrical shell, is also investigated in the results section to evaluate the effect of the structural form on the nonlinear vibration when the MEE layer is added.
