For locating and ranking vibration sources and sinks on structures, the structural intensity (SI) technique is an essential tool. It can enumerate vibration fields by plotting a vector map of energy transmission on the structures. A different strategy, changing coordinate systems of orthotropic plate equations, is used to develop intensity formulation components in both x and y directions. The formulation is carried out in the frequency domain considering flexural waves. Orthotropic plate theory, far-field conditions, Fourier transform, and finite difference approximation are considered. The same intensity definition is obtained using this different strategy.
