The deflection and time response of shape memory alloy laminated composite plate are studied using first order shear deformation theory. The composite plate consists of a thin layer of shape memory alloy bonded to an elastomer layer. The governing equations of the plate are developed using the energy balance equations and a two-dimensional model of the shape memory alloy layer. The finite element is modeled with the first order shear deformation theory and equivalent single layer assumptions. The model is validated by comparing the results of the displacements and time responses with the literature. As a specific example, a cantilever composite plate is used for parametric studies. The effect of material properties, electric input power, thickness, thermal conductivity and heat sink strength on deflection and time response is also investigated.

Free vibration and stability analysis of piezolaminated plates is presented using the finite element method based on higher order shear deformation theory. The distribution of electric potential is assumed as linear through the thickness for each piezoelectric layer. The variation of the temperature field is neglected for the orthotropic layers of the laminate and for the piezoelectric layer. An eight node quadratic isoparametric quad element is employed in the finite element formulation. Numerous parametric studies are conducted for free vibration and stability analysis of a piezolaminated plate with different electric conditions of the piezolayer. The emphasis is on examining the influence of boundary conditions, ply orientation and plate aspect ratio on the free vibration and stability analysis of simply supported piezoelectric laminated plates. The results are verified with other numerical solutions available in the literature and are found to be in good agreement.
