| Abstract: | The bifurcation problem caused by the axial stress wave is disscussed. The elastic ideal column subjected to a step load is analyzed. The effect of lateral inertia on the dynamic buckling is taken into consideration. A proximate method for analysing the post bifurcation is given. The obtained conclusions can be applied in the analysis for bifurcation problem due to stress wave. |
