本文使用动态离焦散斑技术,测试板的动态弯曲获得成功。并推导了Kirchhoff板动态变形的有关分析,提出了由最大斜率确定材料常数的思想。显然,这是同离焦散斑方法所测数据直接相关的处理手法。
In this paper, the dynamic defocus speckle technique is used to test the dynamic bending of the test plate. The relevant analysis of Kirchhoff plate dynamic deformation is deduced, and the idea of determining the material constant from the maximum slope is proposed. Obviously, this is the treatment that is directly related to the data measured by the out-of-focus speckle method.
