Shape memory alloy simulation

Webb22 feb. 2024 · Shape memory alloy (SMA) is a type of smart memory material that undergoes a phase transition when it is subjected to a mechanical loading or temperature change [ 1 ]. SMA has the unique ability to remember its predominated shape and came back to its original shape when the conditions return to normal [ 2 ]. WebbIn this paper, the superelasticity effects of architected shape memory alloys (SMAs) are focused on by using a multiscale approach. Firstly, a parametric analysis at the cellular level with a series of representative volume elements (RVEs) is carried out to predict the relations between the void fraction, the total stiffness, the hysteresis effect and the …
