Abstract

A procedure and software for studying the dynamics of a reinforced cylindrical shell on an elastic foundation are developed. The shell is under local loads distributed over small areas and varying linearly during a short time. The stringers are described by a structurally orthotropic model and the ring ribs by a discrete model. The candidate solution is expanded into series of natural modes. The influence of a local load on the deformation parameters of the shell is studied using a test example. Conclusions on the effect of the pulse shape, the time of action of the external forces, and the reinforcement on the strain state of the shell are drawn
