| Abstract: | The dynamic response of ring-stiffened cylindrical shells under non-uniform and impulsive loading locally and axially is considered. The Hamilton variational principle is extended to derive the equations of motion, taking account of the shear deformation and the rotational inertia in the shells and the stiffeners. And a semi-analytic finite difference method is used to solve this problem. The ef- fects of the stiffeners on the dynamic response to ring-stiffened cylindrical shells is discussed. |
