| Abstract: | n this paper, the plastic buckling of a cylindrical shell under axial impact and subjected to con-stant lateral pressure is analyzed. The variation of the second critical impact velocity preducing non-u-niform or non-axisymrnetric buckling form and the buckling wave number with the lateral pressure arederived, better agreement is found between the results of analysis and experiments. |
