A literature review on energy flow analysis of vibrating structures. Part. I: Interface Energy Flow

With energy flow analysis (sometimes addressed as power flow analysis) is defined the analysis of power transmission between different components of a mechanical systems. In literature different formulations for the definition and the estimation of the energy flow are available. The formulation addressed to Goyder and White in 1980 is mostly suited for low frequency analysis and for the analysis of energy flow at interfaces between structures interacting, while the one introduced by Belov and Rybak in 1975 (also this addressed as energy flow analysis) found many applications in combination with the Finite Element Method (FEM) for the high frequency analysis of vibrating systems. In the first part of this literature review, a general framework for the methodology introduced by Goyder and White, here addressed as interface energy flow analysis, is presented
