The vibration response of a square clamped plate is dependent on the metallographic structure of the material used. Analytical studies of such systems have succeeded in predicting many of the modes of vibration, but experimental verification has been limited by the methods employed. Electronic speckle pattern interferometry offers the ability to study plate dynamics in real time, thus allowing changes of force input on the respective vibration modes to be observed as repeatable events. The study demonstrates the extent to which material characteristics can affect experimental frequency values as compared to theoretical predictions. (Author)
