Sensitivity Analysis of Piezoelectric Material Parameters Using Sobol Indices

  • This computational study examines the sensitivity of the vibrational eigenmodes of a block-shaped piezoelectric test specimen upon variation of the underlying material parameters. The method of Sobol is employed with the calculated resonance positions and their respective electrical impedance as quantity of interest. For this purpose, the FEM-Software COMSOL Multiphysics in combination with MATLAB is used to calculate the resonance frequencies and impedance values as well as a mode shape analysis for eigenmode identification.
