Wavelength Scale Effects on Energy Propagation in StructuresBased on the thermal exchange of mechanical energy, S.E.A. provides information on the stored and dissipated energy and on the transmitted power between coupled dynamic systems. In spite of the particular simplicity of this energetic formulation, the research of a solid theoretical basis of S.E.A. i

On the Validity Domain of Some High Frequency Energy Modelsveloped to describe structural/acoustic response in this field. Recently, new original strategies like the Wave Intensity Analysis WIA or a class of models called Smooth Energy Eethods SEM have appeared to overcome some SEA deficiencies. Two forms of those energy flow methods have been developed. Th

Some Energy Relations for Mechanical Systemsbetween various quadratic vibration characteristics—energy, power flow and others. These relations turn out to be useful for estimating SEA parameters of the system via data measured on a part of the system DOF’s.

The Energetic Mean Mobility Approach (EMMA) the local energies after rigid coupling, on an assembly is exposed. The concept of frequency averaged active power source is also proposed. Numerical simulations illustrate this method for two different homogeneous and heterogeneous substructures rigidly linked at several points.

An Approach to the Statistical Energy Analysis of Strongly Coupled Systemst paper presenting the SEA formulation, Lyon and Maidanik used a light coupling assumption to derive the fundamental power flow equations for two coupled resonators. In a later paper Scharton and Lyon removed the light coupling assumption by redefining the subsystem “blocked” energies. The v

The Energy Flow Equation of Continuum Dynamics subject to boundary conditions. The model is applied to a selection of simple examples to illustrate the concepts of an energy flow density vector, energy flow line, energy potential and an energy equipotential surface. On this basis, a brief comparison between mechanical and therna.l energy flows

Predictive SEA Using Line Wave Impedancesinite plate to plate random incidence transmission coefficients. This paper outlines a method for such a procedure based upon generalising the 1D concept of a point impedance to 2D concept of a line wave impedance. Formulae are presented for the line wave impedance of an infinite Timoshenko beam and

Vibrational Energy Flows between Two Plates Forming an ‘L’-Shape and Joined by Compliant and Dissipas it is assumed that the plates are rigidly joined and that no energy dissipation occurs at the joint, i.e., conservative coupling. In most practical cases, however, the plate elements forming a complex, built-up structure are joined together by welding or fasteners which give rise to energy dissipa
