Abstract: The elastic-plastic dynamic buckling of cylindrical shells under axial non-uniform impact load?ing is discussed. The basic equations of structure are derived from the Hamilton variational principle, and the constitution of materials utilizes the increment theory. Increment numerical method is used to solve the kinetic equations. The deformation model and critical dynamic buckling loads of cylindrical shells under axi?al non-uniform impact loading are discussed and compared with results of the cylindrical shells under static axial eccentric loads and axial axisymmetric impact.
