摘要
本文简述了薄壁结构在剪切屈曲状态下破坏的力学机理和破坏型式;屈曲临界应力的测量方法和寿命估算方法,介绍了试验概况并给出了部分试验结果。
The mechanism and the failure modes of thin-walled structurer under shear-buckling, the measure methods of critical buckling stress and a method of fatigue life estimation are summarised. Also, the general situations of the buckling tests are presented and some test results are provided in this paper.
