This paper addresses some of the problems associated with the use of shape-memoryactuators in Smart structures. These problems include (i) prediction of the straintrajectories during partial actuation, and (ii) the long-term stability of actuation strain.These phenomena are discussed in the context of their implications for actuator control,and the design of structures containing shape-memory actuators.
