Abstract：; Presented static deformation control of a cantilever box beam by using shape memory alloy (SMA) lay-ers. A general analytical model applicable to explicit solution for strain, stress and displacements of the SMA com-posite thin-walled box section beams subjected to thermally-driven was developed. SMA layers model was based on Tanaka' s constitutive equation and Lin' s linear phase transformation kinetics. The force-deformation relationships equations were derived from the classical lamination theory. Numerical results show that significant transverse de-flection can be induced in the thin-walled box section beam during the phase transformation due to SMA actuation.The effects of thickness of the beam wall and the martensitic residual strain of SMA layers are also addressed.
