A dataset for solving stress in three-point curved beam photoelastic experiments based on cubic spline interpolation method

To avoid the lengthy structure of the article and the core information being overwhelmed by redundant expressions, the article did not conduct a detailed analysis of the experimental data processing section. Here, a thorough analysis and discussion are conducted on the experimental data processing link designed in the article on solving the stress of the three-point curved beam photoelastic experiment based on cubic spline interpolation method. At the same time, specific data for theoretical solutions and numerical solutions are provided. Describe in full the entire process from photoelastic experiments to comparative verification and finally to the writing of the thesis
