Abstract: | In this paper, the dynamic buckling of an elastic-plastic column is studied. Let its dynamic buckling under step load be reduced
to a bifurcation problem caused by the propagation of axial elastic-plastic stress wave. The critical buckling condition is
given and the reflection of the elastic-plastic stress wave is taken into consideration. In the end, numerical computation
and conclusions are presented and obtained.
