Abstract:

The shape changes by bending and twisting of a SMA/composite panel with embedded SMA wire actuators controlled by both electric resistive heating and passive elastic tailoring are investigated to realize the morphing wing of unmanned aerial vehicles. Three-dimensional finite element formulations are derived and used to analyze the behaviors of the SMA/composite smart structures. The numerical results show that the shapes of the SMA/composite panels can be controlled by judicious choices of control temperatures, SMA angles, and elastic tailoring. To validate the analytical results, two SMA-embedded curved panels are fabricated and then, their changes in shape are measured by a laser optical sensor when SMA is activated by electrically resistive heating. Both results show excellent correlation.
