| Abstract: | The photoelastical principle and method is used in this paper, to scale down the geometrical size of a structure, to do model design and to manufacture it. The stress freezing under a uniform pressure, slicing and stress analysis are performed on the model. The stress distribution in different sections of the model is determined. The experiment and its results have provided a basis for optimization design and improvement of numerical methods. |
| Keywords: | stress stress-freezing three-dimensional photoelasticity |
