During an intermediate velocity impact in which the duration of loading is an order of milliseconds but shorter than the period of the structure’s first free vibration mode, there is a relationship between impact duration and buckling load. Although this relationship results in higher buckling loads for shorter duration impacts, the precise nature of the correlation depends on a number of factors one of which is geometry. This paper examines a series of longitudinally stiffened panels with varying radii of curvature subject to uniaxial compression. Results are compared to investigate the possibility of identifying behavioural trends relating to geometry.
