Developing the use of domestic photoelastic coating materials to determine the deformation of parts of complex geometric shapes

The paper presents the results of using some domestic materials in the manufacture of photoelastic coatings to study the stress-strain state in the process of strength testing of parts and assemblies of complex geometric shapes. Based on the analysis of the market for domestic materials for the production of photoelastic coatings, several materials were tested, their mechanical and optical characteristics were determined, and the technology for the production of photoelastic coatings was developed. This paper presents comparative results of a study of the stress-strain state (SSS) of a number of samples and products of aviation and space technology of different levels of complexity, prepared with domestic and foreign photoelastic coatings.
