Paper Title:
Modeling of the Cyclic Behavior of Shape Memory Alloys during Localized Unstable Mechanical Response
  Abstract

Experiments have shown that the localization of transformation in NiTi shape memory alloys (SMAs) is an important factor in determining their mechanical response during cyclic loading. A one-dimensional constitutive model for the cyclic behavior of SMAs is presented that takes into account the localization of transformation and transformation-induced plasticity. An internal variable is introduced that characterizes the amount of temperature-dependent cyclic change. The results of simulations at two different temperatures are also presented.
