| Abstract: | Theoritical analysis model of vibratory response of SMA fiber hybrid composite rectangular ply plate is presented in this paper.A piecewise linear hysteretic model is presented to describe the stress strain constitutive relationship of superelastic SMA.The multicell approach is used to obtain the mechanical properties of a hybrid SMA fiber ply.The governing equation of transverse vibratory response symmetric cross ply composite rectangular plate with SMA fibers embedded within the layers oriented in both directions is derived.The model incorporates with the effects of the damping from SMA phase transformation.Approximate solutions are available using mumerical methods based on the model. |

| Keywords: | SMA fiber composite plate transverse vibration superelastic hysteretic damping |
