Abstract

Abstract

Hamilton Principle was used to derive the general governing equations of nonlinear dynamic stability for laminated cylindrical shells in which,factors of nonlinear large deflection,transverse shear and longitudinal inertiaforce were concluded.Equations were solved by variational method. Analysis reveals that under the action of dynamic load,laminated cylindrical shells will fall into a state of parametric resonance and enter into the dynamic unstable region that causes dynamic instability of shells.Laminated shells of three typical composites w ere computed:i.e.T300/5208 graphite epoxy E-glass epoxy,and ARALL shells.Results show that all factors will induce important influence for dynamic stability of laminated shells.So,in research of dynamic stability for laminated shells,to consider these factors is important.
