Abstract. In the paper plane vibrations of an elastic circular structure are analyzed. Investigations of a two dimensional problem are performed. It is assumed that vibrations are taking place. Several first eigenmodes are investigated. Results obtained by using the experimental procedure of stroboscopic geometric moiré are analyzed. By applying the superimposed moiré technique, the results are investigated. Different numbers of gaps are used and provide results of different quality.

Keywords: circular structure, elastic structure, plane vibrations, eigenmode, stroboscopic moiré, geometric moiré, superimposed moiré, experimental results.
