Abstract

Structural-acoustic coupling can significantly alter the dynamic response of coupled systems and is important in predicting sonic fatigue of aircraft skin panels. In the present work, we present an analytical solution for the fully coupled response of a cavity-backed thin plate mounted in an infinite rectangular duct. The plate is subjected to harmonic planar acoustic waves at grazing incidence in the presence of uniform mean flow in duct. The response of a clamped, cavity-backed plate is considered in this study. The theoretical results for a thin panel mounted in a duct are compared with a numerical simulation based on first principles.
