Measurements of the In-Plane Vibration Intensity of a Plate

For the case of the in-plane vibration of a plate, the power is carried by shear and longitudinal waves generating an in-plane two-dimensional displacement field. The objective of this paper is to propose experimental techniques for the measurement of the in-plane vibration intensity (power flow per unit width of a cross section) of the plate. The theoretical basis is outlined for the experimental techniques. The experimental techniques have been implemented to measure the in-plane vibration intensity in the plate. The experimental results of the in-plane vibration intensity in the plate have been compared with the theoretical results. It is shown that the experimental techniques can be effectively used to measure the in-plane vibration intensity in the plate.
