摘要: Abstract An elastically supported viscoelastic functionally graded (FG) microcantilever is considered and its nonlinear mechanics analysed for the first time. Moreover, time, energy transfer via internal resonances motion complexity are analysed. A spring model incorporated as an elastic support which representative of elasticity induced from neighbouring devices. Size effects using modified couple stress theory (MCST). Mori-Tanaka formula utilised FG-material-property variations. Kinematics/kinetics infinitesimal beam elements in conjunction with Hamilton's method used large curvatures. Galerkin's technique reductions truncations dynamic FG microsystem. Both base-excitation/frequency continuations performed dynamics investigated.
