Anotace
The main goal of the project is the research and development of a fully automated optical measuring system for the measurement of the crack growth dynamics during material testing, specifically as an accessory to fatigue testing machines. The measuring device will comprise of an automated image processing and a mechanical manipulator of the optical sensor guided by the evaluation of the deformation data in the area of the root of the crack.
