Nonlinear Theory of Dynamic Stability for Laminated
Composite Cylindrical Shells
摘要
Abstract
Hamilton Principle was used to derive th e general governing equations of nonlinear dynamic stability for laminated cylind rical shells in which, factors of nonlinear large deflection, transverse shear a nd longitudinal inertia force were concluded. Equations were solved by variation al method. Analysis reveals that under the action of dynamic load, laminated cylin drical shells will fall into a state of parametric resonance and enter into the dy namic unstable region that causes dynamic instability of shells. Laminated shell s of three typical composites were computed: i.e.T300／5208 graphite epoxy E-gla s s epoxy, and ARALL shells. Results show that all factors will induce important i nfluence for dynamic stability of laminated shells. So, in research of dynamic s tability for laminated shells, to consider these factors is important.关键词
