摘要：Considering the elastoplastic loading and unloading law, the elastoplastic buckling equation under the stress wave was presented. The dynamic buckling condition was expressed as the bifurcating condition and the buckling force and buckling modes were obtained. The results show that the buckling force of the slender beam is not only dependent on the material constants, but also on the lasting time of impact.
