In this thesis, response distribution in a class of conservatively coupled plates system is investigated experimentally. The ratio of the space-average, time-maximum response of the coupled plates is shown to be proportional to an empiric expression of the space-average time-maximum rotary and transverse receptances, and the time-maximum receptance of the point where the disturbing force is applied, which are parameters open to measurement. The amount of error of estimating response ratio through applying the expression is analysed and found to be small. A brief survey of potential applications of the results of this project to practical structures follows, together with proposed additional work to extend the validity and applicability of the findings. Experimental techniques and apparatus are discussed and described in great detail. An innovation in the experimental set-up is associated with the construction of non-contacting transducer, fitted to a scanning rig, employed to detect response distribution in panel type vibrating elements. Since the experimental apparatus proved useful for the purpose of the project, further work is suggested in order to improve its versatility and develop the rig into an industrial tool, to fulfil a much needed function in dynamic testing. It is suggested that the methods developed in the thesis to estimate response distribution experimentally, have some advantages over present day methods, which is demonstrated by comparing the procedures and some of the basic assumptions involved.
