Shape Memory Effect of Benchmark Compliant Mechanisms Designed With Topology Optimization
Shape Memory Alloys (SMA) are a class of Smart Materials that are ideal for creating compact actuators. The complex nature of their behavior results in the use of these materials in simple geometries (wires, sheets) limiting their performances. A design method to develop complex compliant mechanisms made of SMA is proposed in this paper. Using topology optimization for conventional materials, a set of benchmark problems are designed. Finite element modelling is then able to validate the shape memory effect of the designs (with strain retention up to 80%), confirming the notion that this methodology can, in fact, be used to design the next generation of SMA actuators.
