초록
The finite element method (FEM) and the statistical energy analysis (SEA) are widely used in the numerical analyses of structural vibrations. However, these two methods are limited in that they cannot be applied at high frequencies. In order to overcome this problem, an alternative approach, called energy finite element analysis (EFEA) has been proposed, which is based on power flow analysis (PFA). Because EFEA is the numerical version of a PFA, it is necessary to validate PFA for various structures in order to understand the features of an EFEA. In this study, two different solving approaches (Levy-type and hybrid approaches) of the PFA method are investigated for coupled plates. The predicted results are validated by a comparison with those obtained using the plate theory.
