本文介绍了进行三向应力分析的全息光弹性方法及有关技术，着重分析了全息光弹性方法用于三向应力分析的主要困难在于冻结材料的应力光学常数比Ｂ／Ａ接近-０．５，还提供了一种新的光弹性材料制作和冻结工艺，这种材料冻结时的应力光学常数比可以远离-０．５。用这种材料制成的三维模型可以单独通过全息光弹性方法直接进行一般的三向应力分析。作为一个应用的实例，用这种方法测定了对径受压元球对称断面上的各点应力分量，实验结果和理论解进行了比较。
In this paper, the holographic photoelastic method and related technologies for three-dimensional stress analysis are introduced. The main difficulty of using holographic photoelastic method in three-dimensional stress analysis is that the stress-optical constants of the frozen material are closer to -0.5 than B / A, A new photoelastic material fabrication and freezing process is also provided, where the stress-optical constant ratio of the material can freeze away from -0.5. A three-dimensional model made of this material can be directly subjected to a general three-dimensional stress analysis by the holographic photoelastic method alone. As an example of the application, the stress components of each point on the symmetry section of the ball were measured by this method. The experimental results and theoretical solutions were compared.
