![]() Es beeindruckt vor allem durch seinen großen Dynamikbereich. However, in the narrow frequency bands (150-200 Hz, 200-250 Hz) the sound transmission nature has been significantly affected due to local delamination modes, participating in the fluid-structure interaction process.ĭas Gehör ist mehr als jedes andere Sinnesorgan für die menschliche Sprache und ihre Entwicklung verantwortlich und stellt auf kleinstem Raum ein anatomisch und physiologisch einzigartiges Gebilde dar. The Over All Sound Pressure Level (OASPL) shows that the presence of delamination (40% in total area) in FML has not changed the total energy of the transmitted sound, when compared to aluminium and composites. Sound Transmission Loss (STL) is computed on the panel with center delamination and without delamination. Delamination is introduced in the FE model of FML panel and VA analysis is subsequently carried out. Experimental validation is performed on aluminium panel for verifying the correctness of Finite Element idealization procedure to simulate the fluid-structure interaction. A fluid structure interaction study has been done using Finite Element Method (FEM). ![]() In the present work, the numerical assesment of vibroacoustic (VA) performance of Fibre Metal Laminates (FML) with mid-plane center delamination is presented.
