Abstract: On the basis of a previous paper by the same author, the weighted residual method is further applied to the plastic dynamic response of shells. By using the approaches of collocation and subdomain in the weighted residual method, approximate solution of the plastic dynamic response of cylindrical shells on a medial cross section, when simply supported and under impact loading, are worked out. Also found out are effects of the damping medium on the response.

Key words: cylindrical shells of simply supported, impact loading, Laplace transform, weighted residual method, plastic dynamic response
