Abstract:

Piezoelectric smart structures under strong driving voltages will result in large displacements and rotations, in which electroelastic material and geometric nonlinearities affect simultaneously the structural response. In order to provide a precise model for design and application of piezoelectric smart structures, geometrically nonlinear finite element (FE) models with strong driving voltages are developed based on the first-order shear deformation hypothesis. The proposed models consider both geometric and material nonlinearities, in which the geometrically nonlinear effects include von Kármán type nonlinear, moderate rotation nonlinear and large rotation nonlinear. The present models are validated effectively and accurately through comparison with the experimental data from the literature. Finally, simulations and validations have been conducted through a plate structure and a cantilevered semicircular cylindrical piezoelectric shell structure in terms of the proposed different models to verify the necessity and precision.

Key words: piezoelectric smart structure, strong driving voltage, electroelastic material nonlinear, geometrically nonlinear, finite element model
