摘要
结构冲击屈曲准则是进行结构冲击屈曲分析的基础。然而正是这个基础存在着许多问题，使得完善的结构冲击屈曲理论未能建立起来。本文全面地介绍了诸多学者提出的冲击屈曲准则，讨论了主要存在的问题和适用范围。针对完善结构线弹性冲击屈曲问题的分析。
The impact buckling criteria provide a basis for analyzing the dynamic stability of structures under impact loadings. However, it is just in this basis there exists many problems that hamper the establishment of proper theory of structural impact buckling. The article gives a rather detailed introduction to and discussion on the subject. In the case of perfect elastic structures, a criterion of the transient linear bifurcation is suggested.
