Dynamic buckling of liquid-filled cylindrical shell under axial impact

摘要

In this paper, theoretical analysis and numerical calculation for the dynamic buckling of liquid-filled cylindrical shell under axial impact are carried out. Based on the theory of thin-walled cylinder and the hardening model of rigid-plasticity, the nonlinear dynamic equation is obtained. The unmber of half-waves of axial buckling is calated with the method of amplification functions. The internal pressure of liquid is discussed, and the first and sechond buckling critical velocities are analyzed.
