Dynamic Simulation for Hysteresis in Shape Memory Alloy under Tension

We demonstrate that the Suliciu model is capable to model the hysteresis phenomenon observed experimentally in NiTi shape memory alloy micro-tubes. This model allows a class of stationary phase interfaces. By a series of fully dynamic numerical simulations that mimic quasi-static loading and unloading, the nominal stress--strain curve exhibits a big hysteresis loop, which quantitatively agrees with the experimental results.
