Finite Element Verification and Calibration Example

ABRAVIBE ExamplesPosted by Anders Brandt Nov 12, 2013 19:18
This is a complete example of finite element model verification and calibration (sometimes known as correlation).

The example uses a finite element model built in the free CALFEM toolbox and experimental modal analysis results of the Plexiglas plate used throughout ABRAVIBE as an example structure. The idea of this example is to be simple and illustrative, so that the techniques are not hidden by practical difficulties. The example includes verification of mode shapes using the MAC matrix and frequency tables, and calibration by adjusting the Young's modulus to adjust the first bending mode of the FE model to fit the experimental data. In the Bibliography Section on this site there is a technical paper describing the example.
