Originální abstrakt
Digital image correlation (DIC) as a nondestructive contactless technique for real-time surface deformations measurement have become a powerful tool in various applications. It still has great potential in areas such as fracture mechanics (FM), where crack length is important to evaluate fatigue properties of the material, often measured by travelling microscope. The test is frequently stopped and the microscope is manually used, which takes a long time and the result is strongly dependent on the technician. Automated DIC measurement could help to solve these issues. Therefore, this paper is focused on validation of the method, which would enable such automation and could be more robust and accurate than currently used DIC methods for crack length measurement.
