Abstract
The bending, shearing and torsional components of structural intensity on a vibrating Al ribbed panel were determined experimentally using 9 point finite difference approximations and velocity data obtained with a scanning laser vibrometer. Considering both active and reactive intensities at a global plate mode, the experimental fields were compared with finite element results generated with NASTRAN and McPOW. The reactive intensities compared very well, while active intensities were reasonable. Difference between measurements and finite element data are observed and are likely due to measurement difficulties due to high reverberation levels and the inclusions of near field contributions about the ribs and powers within the ribs themselves.
