Vibration control of rotating sandwich cylindrical shell-reinforced nanocomposite face sheet and porous core integrated with functionally graded magneto-electro-elastic layers

This article presents an analytical approach to study the vibration control of rotating sandwich cylindrical shell-reinforced nanocomposite face sheet and porous core integrated with functionally graded magneto-electro-elastic layers using first-order shear deformation theory of shells. By considering the Coriolis and centrifugal force and also using Hamilton's principle and Maxwell equations, the governing equations of motion for rotating sandwich cylindrical shell are derived. The differential quadrature method is employed to determine the forward and backward linear frequency of rotation sandwich cylindrical shell for different boundary conditions. Detailed parametric studies are carried out to investigate influences of volume fraction of carbon nanotube in face sheet layers, temperature, distribution types of porosity, different boundary conditions, angular velocity and electrical and magnetic control coefficients on vibration control of sandwich cylindrical shell. The results of the necessary parameters can be used as benchmarks for design in important industries such as low- or high-speed rotor and turbine manufacturing.
