Özet

In this study, free vibrations of rotating, multi-layer, adhesively bonded beams are considered. The beam layers are modeled as Bernoulli-Euler beams taking into account nonlinear strain-displacement relations. The thin adhesive layers are considered as distributed, linear, compression-tension and shear springs with elastic constants related to the adhesive material characteristics. The nonlinear governing equations and the appropriate boundary conditions are developed by means of the Hamilton's Principle. The coupled governing equations are then linearized about quasi-static undisturbed state. The problem is then reduced to a generalized eigenvalue problem by employing the Integrating Matrix Method. Some parametric studies are presented.
