✦ Synopsis

Recent developments in adaptive composite structures with distributed multifunctional actuators and sensors have attracted signi®cant attention in the research community due to their potential commercial bene®ts in a wide range of applications such as vibration suppression, shape control and noise attenuation.In the ®eld of ®nite element modeling, very few composite shell elements with electromechanical properties have been reported in the literature. Also, the reported ®nite elements used to model aircraft components have not properly accounted for the eects of curvature, thus requiring re®ned meshes in order to capture accurately the physics of the problem. The model proposed in this investigation consists of a shell type adaptive composite ®nite element with electromechanical properties and with double curvature. Its application in aircraft ¯utter and internal noise suppression are investigated.
