The dynamic system under multi-excitations will expresses more complicated characteristics.In recent years, there have been some researches on nonlinear combination dynamics of laminated composite plates.Nayfeh [1] and Kapitaniak[2] discussed the nonlinear resonances of Duffing system under multi-excitations;Udar Ratnakar et al.[3] investigated the combination resonance characteristics of laminated composite plates subjected to non-uniform harmonic edge loading;Bi[4] and Yang et al.[5] studied the bifurcation in a nonlinear Duffing system with multi-frequency external periodic forces.
