Abstract
This paper presents a finite-element model for the free vibration analysis of a shapememory alloy (SMA) surface laminated composite cantilever plate. The proposed device isconsidered to undergo small displacements and small strains. The governing equations aredeveloped utilizing the first-order shear deformation theory, energy balance equations andtwo-dimensional model of the SMA layer. The finite element is modelled using first-ordershear deformation theory and equivalent single-layer assumptions. The plate isconsidered with clamped-free boundary conditions, and the SMA layer is at thetop of the composite plate. Parametric studies are conducted to study the effecton free vibration of varying the SMA volume fraction, the temperature of theSMA, and the thickness, width and stiffness of the composite cantilever plate.
