Abstract
The real time technique of time-averaged holographic interferometry has been applied to determine the natural frequencies and the corresponding mode shapes for the transverse vibrations of clamped wedge-shaped and ring-shaped sector plates. Over 200 resonant modes have been obtained for wedge-shaped sector plates and over 170 for ring-shaped sector plates. The natural frequencies obtained have been expressed in terms of a dimensionless frequency parameter, and the results are shown graphically as a function of the sector angle for the wedge-shaped plates and of the radii ratio for the ring-shaped sector plates, respectively. Some of the present results for wedge-shaped plates are compared with the analytical values obtained by other authors.
