Application of laser shearography to vibration mode shape analysis of composite panel during acoustic load
Original language description
Acoustic fatigue is important topic of durability in aerospace. Progressive wave tunnel was built to carry out the tests of acoustic fatigue properties of flat composite panels. Vibrations were induced by sound wave. The mode shapes of the vibrations of panel were measured by laser shearography in a form of shearograms – fringe patterns of the out-of-plane surface displacement gradients. Finite-element modal analysis of the panel was performed. FE based displacement gradients were compared with shearograms. Excited vibration mode shapes can be qualitatively estimated on the basis of these comparisons. Few suggestions to enhance both the resolution of shearograms and FE analysis were made.
