Fascinating properties of shape memory alloys, being shape memory effect and super-elasticity, make them unique in comparison to other materials. One of the most common applications of these materials is in actuators as an actuation mechanism. In this research, a shape memory actuator is presented and modeled. The Souza et al. constitutive model is employed in finite element analysis software in order to simulate the shape memory behavior of Nitinol. Ti-49.8%Ni was selected according to the proper characteristics, and its mechanical properties are characterized through experimental tests to the calibrated model for this alloy. The simulation results were further verified by empirical evaluation of a Nitinol actuator.
