Impact dynamic response analysis of composite stiffened shells has been carried out using finite element method. As there is no published literature available on the impact dynamic response of composite stiffened shells, the finite element technique has been applied using a nine noded Lagrangian element for obtaining new results. An improved version of the stiffener modelling has been used in which stiffeners can be placed inside the element. The results of stiffened composite doubly curved shells with different boundary conditions and various laminae orientations have been presented for eccentric stiffeners.
