Shape Memory Alloy(SMA)has advantages of great recovery stress and elastic modulus varied with the temperature, so it can be embedded in composite structure to active control structure deformation and vibration. In this paper, we have deducted the recovery stress at different temperature by modifying the phase-change coefficient Ω of Liang Constitutive Model[1], then base on = /E equation, the recovery stress is translated into recovery strain. By using finite element software ANSYS, the natural frequency of composite plate at influence of recovery stress can be obtained under both ends of fixed conditions at three configurations. The steady-state vibration response of the composite plate embedded SMA fibers is also simulated. The results show that recovery stress of SMA can increase the natural frequency and can suppress vibration effectively.
