In various kinds of shape memory alloy (SMA), Fe-based SMA (Fe-SMA) shows smaller shape memory effect compared with the other SMAs. However, Fe-SMA shows huge advantages on the excellent formability, machinability, etc. Therefore, it is attempted that the alloy is applied to structural members such as joints and dampers. In this study, at first, the bending strength and its rate sensitivity of the joints made of Fe-SMA are experimentally estimated by the three-point bending test at various deformation rate. Then, it is challenged that the force balance equation is derived to predict the bending strength.
