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.

Digital Image Correlation Method

Interface damage characterization and interlaminar failure of sandwich specimens with two initial interlaminar defects (inserts) is done by using the digital image correlation method. Mode I tests reveal interesting particularities on damage localization and unstable crack propagation. After analyzing the experimentally obtained results, we propose as a failure parameter the local strain at the crack tip or, alternatively, the crack tip opening displacement which quantifies the non-linear phenomena.
