Abstract: The dynamics of a multi-layer composite plate with delaminations subjected to an aerodynamic load is analysed. A finite element model to predict the dynamic response of the system with embedded shape memory alloys (SMA) fibres is proposed. The effect of delamination on the natural frequencies of the plate subjected to supersonic flow is studied, and the flutter instability boundaries are determined. The numerical model developed is applied to show that the SMA fibres can be applied to modify these boundaries. Thus, a SMA-based control system can be designed to reduce the adverse dynamic response of composite structures due to flutter phenomena
