Analyse dynamique d'une poutre linéaire avec une interface non linéaire

Abstract : The dynamical study of a beam coupled with a thin beam is performed. Assuming that the beam's behaviour is linear and that the thin beam can be replaced by nonlinear springs located at the interface beam/thin beam, a dynamic substructuring method allows to model the whole structure. With harmonic excitations, the harmonic balance method is used to change the differential equations into non linear algebraic ones in the frequency domain that are then solved by using a continuation method. This procedure is then applied to a real benchmark and the comparison with experimental results allows to check the efficiency of the method.
