Evaluation of corrugated composite beam deflection by shape memory alloy wire

In this study، the corrugated composite beam is actuated by shape memory alloy wire (SMAw). SMAw was placed on the surface of composite beam. Martensite to austenite transformation occurs by increasing of SMAw temperature. After transformation، SMAw length decrease and beam actuated. Beam displacement، force and current are measured and by A/D board transferred to computer. For evaluation of temperature in SMAw، the Heat transfer differential equation is used. Also Brinson’s model is used for modeling of SMA behavior. The results show that SMA behavior in Brinson’s model is good agreement whit experiments. But in lower temperatures than martensitic transformation state، the SMA stress is equal to zero in experiment unlike Brinson’s model. Also considering the SMA training and DSC test، for some temperatures in the experimental results، the start and end transformation temperatures are different to Brinson’s model. The results show as using SMAw in the corrugated composite، smart structures can be achieved that in corrugation direction is irritable، whereas in Perpendicular to the direction، corrugated composite bending strength is high that lead to using this structure in engineering application.
