The experimental photoelastic method, which is a continuum method, and the method of forced deformations defrosting, allow us to obtain a stress-strain state in the stress concentration zone on the contact surface of composite structures with a surge of forced deformations on models made of optically-responsive material. The experimental solution is obtained on the model with an angular cut of the boundary, the vertex of which is occupied by the rupture of forced (temperature) deformations. The fringe contour obtained on the model by photoelastic method and the method of defrosting in the stress concentration area, in the zone of angular cut of the boundary and forced deformations surge, is characterized by significant gradients of experimental data: the order of fringes (isochromes), isoclines parameters, stresses, deformations. Modern methods of visualization of experimental data based on digital shooting expand the capabilities of the photoelastic method. The study purpose is to estimate the capabilities of using photoelastic method and the method of deformations defrosting to obtain the stress-state deformation in the angular zone of a region, which is as close as possible to the stress concentration area during digital shooting and data processing, by the standard methods of stress separation.
