Vibration analysis of laminated cylindrical thin panels with twist and curvature

Using the principle of virtual work and the Rayleigh–Ritz method with two dimensional algebraic polynomial displacement functions, the governing equation of vibration for a laminated cylindrical thin panel with twist and curvature is presented. The practicability and effectiveness of the method is verified by comparing the numerical results with those obtained by other researchers using experimental and other numerical methods. The effects of twist, curvature, characteristics of material, the number of layers, stacking sequence and fiber orientation on vibration frequency parameters of a laminated cylindrical thin panel with twist and curvature are studied, and some vibration mode shapes are also plotted to explain the variations of the vibration caused by them.
