The measurement of vibration power flow in structures is very useful for studying noise and vibration problems in industry. In this article the structural intensity technique is used to formulate in-plane wave power flow in naturally orthotropic plates. A new analytical vibration power flow model is developed in the frequency domain. This model requires only one cross-spectral density function of the field signal to obtain the magnitude of the intensity vector of power flow in a chosen direction at a particular point on a plate. This new model does not depend on far field approximations.
