Study on Buckling Behaviour of Laminated Shells Under Pulse Loading

This experimental and numerical study focuses on the buckling problem of cylindrical composite shells under pulse loads. Series of experiments have been performed to determine buckling loads of the laminated cylinders under different axial loading rates. Numerical models of the tested specimens have been elaborated and good agreement between experimental and numerical results has been achieved. The numerical models have been used to study the buckling behavior of the cylinders at loading rates much higher than could be achieved experimentally. Additionally, the influence of imperfections on dynamic buckling behavior of the laminated shells has been studied numerically.
