Smart structures that used the Ni-Ti shape memory alloy in order to develop mounting/dismounting equipment for the radiation protection clothes were produced experimentally. This is merely an instance. 2 kinds of test specimen of the high-temperature closing and high-temperature opening type were fabricated. The analytic solutions on reversible shape change and tightening force or pressing force for these models were deduced. It could be verified that the analysis method in this study was appropriate, because experimental value and analytic value agreed well. Therefore, it was clarified that the real equipment that it is elaborate and that there is the reliability could be made, if present analysis method is used.
