Determination of flexural wave power in freely suspended isotropic plates for far field conditions using vibration intensity

Far field vibration power and input power were estimated in freely suspended isotropic steel plates using two-transducer method. Fourteen measurement locations in two lines: one at the middle and another one at the closer to lower end damping area of the plate were considered for estimating far field power. The far field power was compared to the mechanical input power injected to the plate. In all respect, the far field power was less than that of the input power injected. The values of resonance peaks were lower in magnitude in the region closer to end damping area.
