Directivity pattern of a cantilever plate. Comparison of numerical results with experimental data

For a cantilever aluminium plate, the vibration modes were investigated experimentally by means of the Chladni method and numerically with the FE-method (NASTRAN). The sound radiation of three selected eigenfrequencies was determined by the reciprocity method and was calculated with a coupled FEM/BEM-approach. The comparison of the experimental and numerical results shows excellent agreement.
