Fiber glass), the mechanical strength of the insert of metallic material and the relevant damping properties of SMA, in the martensitic phase. Embedding the SMA layers in composite structure allows to combine different properties: the lightness of the base composite (e.g. This work describes the design and optimization of a hybrid layered composite structure for the passive suppression of flexural vibrations in slender and light structures.

Among the different materials available to achieve damping, much attention has been attached to the use of shape memory alloys (SMAs) because of their unique microstructure, leading to good damping capacity. The intelligent approach to address the problem would be the use of materials which are more capable in dissipating the energy due to their high value of loss factor. A brief description of the model is presented, followed by discussion of implementation and usage in the commercial codes. The model is also relatively easy to use and requires input of only fundamental engineering properties. The model may be easily implemented in any code that has the capability for analysis of laminated composite structures with temperature dependent material properties. A thermoelastic constitutive model for shape memory alloy ( SMA) actuators and SMA hybrid composite (SMAHC) structures was recently implemented in the commercial finite element codes MSC.Nastran and ABAQUS. It was established that dynamic behavior of the smart hybrid composite plate depended on various parameters such as volume fraction, temperature dependent recovery stress and tensile pre-strain of SMA wires and aspect ratio of the laminated hybrid plate. For simply-supported boundary conditions, systematic closed form solutions were obtained by Navier's technique.
