摘要
本文给出了研究抛体大变形的实验测试方法.用该方法测定了金属板变形的Lagrangian位移和Lagrangian速度,得到了金属板变形过程的真实位移场.讨论了实验结果,并与前人的工作作了比较,实验效果较佳.
This paper presents an experimental method of determining large deflections of structures. Using the method, Lagrangian displacement and Lagrangian velocity of metal-plate deflections is measured. The paper reviewed other's previous works and progresses made. The obtained results is satisfactory.
