Due to their advantageous characteristics, shape memory alloys (SMAs) are prominent representatives in smart materials. They can be used in application fields such as soft robotics, biomimetics, and medicine. Within this work, a fiber-elastomer composite with integrated SMA wire is developed and investigated.

This work discusses the design, manufacturing, modeling, simulation, and feedback control of the actuator. The SMA wires are encased in Polytetrafluoroethylene (PTFE) tubes and then integrated into the 3D-printed matrix made of thermoplastic polyurethane (TPU).

- * Shape memory alloys (SMAs) are key smart materials being applied in various commercial and research settings, requiring effective modeling to maximize their potential; however, existing finite element models have limitations.
- * The study focuses on validating a new SMA material model by Woodworth and Kaliske, which accommodates pre-stretching in irregular geometries, against the Souza and Auricchio model, to improve accuracy in predictive analysis for SMA systems.
