Abstract
The experiments were carried out at Institute of Physics, Prague to enhance the actuation frequency of Shape Memory Alloy (SMA) actuators. The fast actuation is critical for many applications particularly those involving aerospace. Various experiments have been conducted and detailed study has been made regarding the improvement in the actuation frequency and its limitation. During these experiments parameters such as strain, stress, temperature and resistance have been measured. More insight into thermo-mechanical characterization of different diameters of SMA wires has been obtained. Some experiments were also conducted to study the thermomechanical and electrical resistance behavior of super-elastic SMA wire during the tensile testing.
