摘要
Results of experiments on loading a pack of closely packed metal plates by an oblique shock wave are reported. Buckling of the interface between the plate is observed. It is shown that periodic wavy perturbations are formed due to the development of the Kelvin-Helmholtz instability within the time of interface turning induced by the shock wave action. The final amplitude and wavelength of perturbations are found to be determined by the thickness of the weakened layer in a plastic flow.
