An investigation was conducted to determine the effect on fundamental frequency of changes in the boundary conditions of circular plates. Two cases were investigated the circular plate, clamped on part of its boundary and simply-supported on the remainder and the circular plate, clamped on part of its boundary and free on the remainder. The methods of analysis used were experimental measurement using laser holography, finite-element, and a modal approximation. Results were compared for the different methods and with some results available in the current literature.
