Structural intensity fields of naturally orthotropic plates

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.
