Research of the non-uniform strain and displacement fields in solids with concentrators with the use of the DIC technique

This work focuses on analyzes the non-uniform strain fields in the area of stress concentration and study the limiting stress-strain state of the material in the test samples with different geometry concentrators with the use of the measuring system non-contact three-dimensional digital optical system Vic-3D. The research included tensile mechanical tests on flat samples with a hole research of the damage and failure processes of materials.
