The dynamic response of plates and cylindrical panels with various curvatures under external lateral pressure pulse was studied. Nonlinearities due to large deflections were included and the dynamic response was analyzed using a finite element code. Effects of shell curvatures, pulse durations and load intensities were investigated. The observed dynamic behavior included also non-linear shell buckling due to the compressive stresses under the external pressure on the cylindrical panels. The results, when compared to the linear response, show the effects of the increased load intensity and the resulting non-linear behavior on the response to various pulse durations. Also, the differences between the static and the dynamic behaviors for similar load intensities were studied. Non-dimensional processing of the results, including in the large deflection range, highlights the effects of high load intensities on the structural stiffness and in turn on the changing characteristics of the response under a given pulse duration.
