Nonlinear Vibration of a New Three-Phase Composite Cylindrical Shell
摘要
In this paper, the nonlinear vibration response of a new three-phase composite cylindrical shell made of epoxy resin, graphene nanoplatelets and carbon fiber is studied. Based on the first-order shear deformation theory and the von-Karman geometric nonlinear relation, the nonlinear partial differential equations of motion of a new three-phase composite cylindrical shell are established by Hamilton principle, taking into account the interaction of hygrothermal, aerodynamic force and external excitation. The Galerkin’s method is combined with the pseudo arc-length continuation solution to address the internal resonance problem of nonlinear systems. In this paper, the impact of moisture difference and external surface excitation on the nonlinear forced vibration response of a new three-phase composite cylindrical shell is studied
