| Abstract: | Abstract: The article deals with the possibility of using digital image correlation method in experimental determining of damping ratio. The essence of the article is a proposal of algorithm for the processing of a time responses measured by correlation system Q-450 Dantec Dynamics. The algorithm uses a Fast Fourier Transformation and bandwidth method to calculate a damping ratio. The output is a graphical representation of the value of damping ratio for given natural frequency of the test object. The article presents the method of verification by testing algorithm on numerical models and its practical application in determining the value of damping ratio of a specimen material.
