Natural frequencies and the corresponding mode shapes of circular cylindrical shells were experimentally investigated by time-averaged holographic interferometry. The shells used in the experiment had two kinds of boundary conditions, one of which was clamped at one end and free at the other, and the other of which was clamped at both ends. The natural frequencies which were measured ranged from 1137 to 7758 Hz, and the fifty-nine mode shapes were obtained. Some rough tendencies could be identified, although an exact conclusion could not be drawn due to insufficient numbers of experimental samples.
