Suppression of the Snap-Through Behaviors of Composite Shell Structures Using Piezoelectric Actuator

摘要：

Cylindrical composite panels show uncommon structural instability behaviors due to its geometrical characteristics.Especially,the snap-through phenomenon may affect the appearance of the crack or the delamination that could induce the collapse of the whole structure.Therefore,the snap-through behaviors should be suppressed for the structural stability.In this research,the suppression of the snapthrough behaviors of composite shell structures with piezoelectric actuators is investigated by using a finite element method.The arc-length method is applied to predict the snapping behaviors.The effects of attaching positions of Micro Fiber Composite(MFC)actuators are shown to increase the critical snapping load with various curvatures of cylindrical panels.
