The study of the steel/steel adhesive joint using digital image correlation method has been carried out. A correlation between the evolution of distributions of deformation regions on the surface of the adhesive joint and the stages on the deformation curve is revealed. It has been found that a destruction along the adhesive seam begins when the adhesive joint reaches total deformations of about 0.5%. The analysis of deformation fields on the steel surface have allowed revealing the formation of extensive tension regions with greatest deformations at the interface of loaded plates. An increase in the values of compression deformations at the ends of the patch and a significant increase in the areas of these regions have been revealed.
