| 摘 要： | 受轴向冲击载荷作用的弹性杆的屈曲问题曾被许多作者从不同的角度研究过。本文以半无限长弹性直杆为研究对象,把这个问题作为由于轴向应力波的传播而导致的分叉问题,给出了它的正确提法,并通过实例作了具体的说明。

| Abstract: | In this paper the buckling of the ideal straight elastic bars subjected to the axial impact is studied in connection with the bifurcation due to the stress wave propagation. In this new formulation the critical states of buckling (bifurcation points) can be found, which have been ignored in previous investigations. |

| Keywords: | impact bifurcation buckling stress wave. |
