Abstract
Numerical applications of the approach presented in a companion paper is proposed for the cases of coupled beams and coupled plates. Results are compared with other calculations. CLF calculations for coupled beams are achieved with an analytical modal description. The influences of thickness ratio and damping on the quality of the prediction are presented and discussed. CLF determination with an FEM modal description are then applied to the case of two thin plates coupled in an L shape. This case allows comparison with other calculations and will be a representative of the applicability of the method to more complex structures such as industrial ones. The good agreement with other methods validates the calculation of CLF with the present method.
