摘要: Nonlinear modal interactions in the forced vibrations of a thermally loaded pre-buckled annular plate with clamped–clamped immovable boundary conditions are investigated. The mechanism responsible for interaction is combination internal resonance involving natural frequencies three lowest axisymmetric modes. in-plane thermal load acting on assumed to be and externally excited by harmonic force. nonlinear von Karman equations along heat conduction equation combined model behavior system. An analytical/numerical approach used examine excitation near primary one
