Abstract
The application of the original optical image recognition program Edge for measurement and analysis of the displacement and strain rate during a dynamical test on the flywheel device was presented in the paper. Examples of image recognition analysis on a movie taken by high-speed camera Phantom v12 were used, in connection with the software, as dynamical videoextensometer. The results showed that the previously assumed constant velocity of the lower end of specimen during flywheel device test is not true.
