A new strategy for far-field power transmission in orthotropic plates

Vibration intensity (VI) technique is an essential tool for locating and ranking vibration sources and sinks on structures. It can quantify vibration fields by plotting a vector map of energy transmission on the structures. In this paper, a new strategy, by changing coordinate systems of plate equations, is used to develop an intensity equation from shear force component both in x and y directions. The formulation is carried out in frequency domain considering flexural waves. Orthotropic plate theory, far-field conditions, Fourier transform, and finite difference approximation are considered.
