▎ 摘　　要

This paper reports a result of investigation on the nonlinear resonant characteristics of graphene/elastic/piezoelectric (GEP) asymmetric laminated films under exciting electric loading, based on nonlocal elastic theory and von Karman strain-displacement relations in an active control system. The nonlinear dynamic governing equations containing deflection function, stress function and electric potential function are firstly constructed by Hamilton's principle, then are solved by the iterative homotopy harmonic balance method. Results show that the nonlinear resonant frequency of GEP laminated films can be controlled by adjusting the voltage exerted on piezoelectric layer according to engineering requirement, and the material property of elastic layer has a significant effect on the nonlinear resonant frequency of GEP laminated films, where the nonlinear behavior of resonant frequencies increases as the ratio of vibration amplitude to thickness of laminated films increases.
