Une nouvelle stratégie de calcul en dynamique transitoire recouvrant les basses et moyennes fréquences pour des structures complexes

Abstract : The paper deals with a new computational method for transient dynamic analysis which enables one to cover both the low-and medium-frequency ranges. This is a frequency approach in which the low-frequency part is obtained through a classical technique while the medium-frequency part is handled through the Variational Theory of Complex Ray (VTCR) initially introduced for vibrations. The aim of the paper is to extend the capabilities of the method to engineering systems.
