The　restrained　shape　memory　alloy(SMA)layers,　as　actuators,　are　pasted　on　the　surfaces　of　the　structure.　Upon　heating　the　layers,　the　martensitic　residual　strain　will　be　restored,　the　large　recovery　forces　are　induced　so　that　the　structure　will　deform.　A　mechanic　model　of　a　beam,　the　simplified　wing　or　blade,　covered　with　an　induced　strain　actuator　(a　SMA　layer),　is　presented.　The　mixed　deformations　of　compression　and　bending　of　the　beam　with　SMA　layer　bonded　to　one　surface　aligned　with　the　beam　axis　are　analyzed,　and　the　analytical　expressions　of　strains,　bending　slope　and　deflection　of　the　beam　are　given.　The　theoretical　predictions　are　validated　with　static　experiments.
