The Initial Imperfection Amplified Criterion is applied to investigate the geometric nonlineardynamic buckling of statically preloaded ring-stiffened cylindrical shells under axial fluid-solid impact.Tak-ing account of the effects of large deformation and initial geometric imperfection,the governing equations areobtained by the Galerkin method and solved by the Runge-Kutta method.The effects of static preloading(uniform external radial pressure)on the buckling features and the load-carrying ability of ring-stiffened cy-lindrical shells against axial impact are discussed.
