The study is focused on experimental and analytical evaluation of combined vibroacoustic-elastic response of composite structure, subjected to broadband random vibration. The number of studies on this particular topic is relatively small, though the understanding of structure response to jet noise and generating of related S-N data are essential for composite aircraft sonic fatigue certification.
