Mathematical Modelling of Shape Memory Alloy Effect (original) (raw)

Even it has been already confirmed that SMA's have high potential for robotic ac- tuators, actuators included in space robotics, underwater robotics, robotics for logistics, safety, as well as "green robotics" (robotics for the environment, energy conservation, sustainable de- velopment or agriculture), the number of applications of SMA-based actuators is still quite small, especially in applications in which their large strains, high specific work output and structural integration potential are useful,. The paper presents a formulated mathematical model calculated for binary SMA (Ni-Ti), helpful to estimate the stress distribution along with the transformation ratio of a SMA active element.
