应用激光双底片散斑内涂层法求解三维应力问题

Study on the Three-Dimensional Stress Problem Using Laser Double Plate Speckle Method With a Inside Coating

概述了利用双底片散斑照相技术测量物体表面位移的方法。在透明模型内部待测截面涂上一层漫反射层,即可测得该截面上的位移和应变。

The method of measuring the surface displacement of a body was described by the aid of double plate speckle photography. If a diffuse reflection layer is coated at the interested section inside a transparent model, the displacement and strain at the measured section can be obtained by using above method.
