In Chap.7, we covered the basics of SMA wire and spring design for dead loading conditions. We noted that if the stroke required is very large, a simple SMA wire may be unfeasible.Thus, successful design of a shape memory wire actuator depends upon the ability to combine it with a mechanism to achieve the desired force and stroke when actuated.
