The subject of the work is to present the possibility of using a non-contact optical system for measuring strains. Dantec's multi-unit Q-400 3D image correlation system was used. The aim of the work was to determinate the distribution of displacements and deformations on the surface of samples with different cross-sections and made of different materials during the bending test. The measurement was used basically to estimate the deflection line of the bending beams and at different points of the cross-section. Measurement was carried out by tracing the displacement of the prepared surface of the bending sample. In the paper, the results of the studies show the displacement and deformation fields for different bending steps of flat samples. A numerical model of the bending process was also developed to compare the results with experimental studies.Keywords: displacements, 3D image correlation system, bending test.
