The boundary Accepted 14 April 2014 condition is considered to be immovable simply support. The Galerkin method is used Available online to obtain the nonlinear ordinary differential equation in terms of an unknown time 16 April 2014 function. The obtained equation is solved analytically by the multiple time scales Keywords Hybrid composites method. The obtained results are compared with the numerical solution of the Nonlinear forced vibration nonlinear ordinary differential equation of motion and a good agreement is found Analytical modeling between them. 2014 Growing Science Ltd.

Fiber metal laminates FMLs are hybrid materials comprising interleaved metal sheets and fiber-reinforced polymer layers. They were developed as lightweight alternatives to structural metals Langdon et al. 2009 . One of the advantages of FML materials when compared with conventional carbon fiber epoxy composites is the low moisture absorption due to the barrier of the outer aluminum layers Botelho et al. 2006 . The only commercially used FML is Glare which comprises thin aluminum sheets and glass-fiber- .
