Abstract:		In this work, we describe digital image correlation method: basics of the method, advantages over other optical methods and a field of application. Tests were conducted by bending of cantilever and pressure of hip prosthetic. The results of bending of cantilever obtained by the digital image correlation method are compared with the measurements obtained with a micrometer. By results of the hip prosthetic test we can judge about strain field distribution and we can evaluate the most deformed area. The results of experiments were processed by VIC-SNAP and VIC-3D. A field of displacement and field of deformation are presented at digital format. The system of digital image correlation provides a full picture of the distribution of strains in a sample. That allows receiving more data based on the results of standardized experiments (tension, pressure) without resorting to numerical calculations by the finite element method.
