Abstract

THE PRESENT STUDY INVESTIGATES NONLINEAR FORCED VIBRATION OF DIELECTRIC ELASTOMER–BASED MICRO-BEAM. THE NONLINEAR TERMS IN BEAM EQUATION ARE GEOMETRIC AND MATERIAL ONE. GEOMETRIC NONLINEARITY IS CONSIDERED BY VON-KARMAN STRAIN DISPLACEMENT RELATIONSHIP AND THE MATERIAL NONLINEARITY IS MODELED WITH YEOH HYPER-ELASTIC MODEL. GALERKIN AND MULTIPLE SCALE METHODS SOLVE THE GOVERNING EQUATION. THIS SOLUTION THAT INCLUDES PRIMARY RESONANCE, LEADS TO FREQUENCY RESPONSE, SO THAT WE DEPICT INFLUENCE OF DETUNING PARAMETER ON AMPLITUDE IN VARIATION OF DIFFERENT PARAMETERS.
