Abstract 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.
