| Abstract: | In an analysis of the dynamic response of a simply supported short cylindrical shell under cosine pulse loading, only the membrane stresses dominating during the early stage are considered. The dynamic equations of circumferential stress and axial stress are derived and solved by double Fourier series which satisfies the boundary conditions at shell ends. The calculation results show that the effect of cylindrical shells on the membrane stress response is significant. In general, the membrane stress increases with an increase of the shell length. |
