High frequency vibration of aircraft structures

Abstract

Research on high frequency vibration of aircraft structures at Southampton, like that on jet noise, pre-dated the foundation of the Institute of Sound and Vibration Research by some ten years. Accordingly, the development of the subject over the past twenty years is reviewed in this paper, with emphasis on both fundamental and applied aspects with which I.S.V.R. research has been particularly concerned. Topics discussed include the following: vibration of stiffened skin panels, vibration of curved panels, vibration of skin-rib structures, damping of structures, wave propagation in periodic structures (one-, two- and three-dimensional) vibration design data, dynamic properties of carbon fibre reinforced plastics, acoustically induced fatigue crack propagation.
