A two-dimensional finite element analysis of a shape memory alloy laminated composite plate

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.
