| Abstract: | This article presents the results obtained while investigating the behavior of cylindrical laminated shells under suddenly applied lateral pressure. The investigations were based on a finite-element approach using an explicit time integration scheme. The Budiansky-Roth and phase-plane criteria were used to assess buckling. The response of the shells was investigated with and without statically applied preloading. Results are presented for different values of shell length, imperfection amplitude, shell total thickness, and laminae stacking sequences, and for different magnitudes of the static preloading. The results presented here can be used in the design of shell structures and can help better realize the influence of the variations in the system parameters upon the shell strength and stability. |
