KEY WORDS

Digital Image Correalation, Experimental Modal Analysis, Modan.

ABSTRACT

The paper deals with digital image correlation method that belongs to the most modern optical method used in experimental mechanics. The main attention is devoted to an application of this method in determination of modal parameters. There is described a methodology of measurement of eigenshapes and eigenfrequencies by high-speed correlation system Q-450 Dantec Dynamics. A part of this procedure is software called Modan that was designed and created as effective tools for evaluation of such type of experimental measurements.
