La Théorie Variationnelle des Rayons Complexes pour le calcul des vibrations moyennes fréquences

Abstract : A new approach named the “Variational Theory of Complex Rays” is introduced for computing the vibrations of elastic structures weakly damped in the medium frequency range. Emphasis has been placed here on the most fundamental aspects. The effective quantities (elastic energy, vibration intensity…) are evaluated after computing a small system of equations which does not derive from a finite element dicretization of the structure. Numerical examples related to plates show the interest and the possibilities of the VTRC.
