Vibration Characteristics and Its Active Control of Smart Functionally Graded Circular Cylindrical Panels in Thermal Environments

Based on the higher order shear deformation theory and the Hamilton principle, this article derives the equations to govern the displacement and electric potential of smart functionally graded (FG) circular cylindrical panels with surface embedded on actuator and sensor layers. The analytical solution considering simply supported boundary conditions is based on the Navier solution procedure. Negative velocity feedback control is used. Numerical results show the influence of (a) different volume fractions of FG material layer, (b) different temperature change of inner surface, (c) different central angle of circular cylindrical panels, (d) different piezoelectric material (PZT-4, BaTiO3, PZT-5A), on the vibration characteristics of smart FG circular cylindrical panels in thermal environmental.
