Abstract
The use of shape memory alloy actuator in high-technology application is increasing. Shape memory alloys became an important material due to its capacity to shape recovery when subjected to a thermomechanical load. This work aims to develop an experimental investigation of linear shape memory alloy actuator using stress-assisted two-way memory effect. An experimental apparatus is built to characterize a linear SMA actuator bias spring. Several situations are investigated highlighting the general thermomechanical behavior of the system. The experimental results show that the characterization methodology used can be employed for design purposes, defining the best configuration and parameters according to the desired actuation conditions.
