Three-dimensional static and free vibration analysis of laminated cylindrical panel with viscoelastic interfaces

In this paper, three-dimensional theory of elasticity is employed to investigate bending and free vibration behavior of simply supported cylindrical panel with special emphasis on incorporating viscoelastic interfacial imperfection. Analysis is carried out by using Fourier series along the axial and circumferential directions and state space technique along the radial direction. Time-dependent behavior is investigated by solving first-order differential equation of sliding displacement at the viscoelastic interfaces. Numerical results depict good agreement between the present numerical results and the available published results. In addition, the effects of solid, elastic and viscous interfaces, time, aspect ratio and mid radius to thickness ratio on the bending and vibration behavior of laminated cylindrical panel are discussed.
