This paper discusses three-dimensional normal projections for three-dimensional photoelastic section stress observations and calculation methods. Discusses the observation requirements of the boundary elements of the section, the accuracy requirements of the section stress, the adjustment of the normal stress, and the reverse order method to improve the precision, etc. The article discusses three projections. The method of observational calculation and calibration of surface point edge stress, the method of calculating the stress component of the section stress coordinate system from the edge stress at the boundary point of the section line, etc. This paper gives various calculations using calculators TI-58 and TI-59. The program provides the conditions for the automated processing of photoelastic data.
