Modeling of the Cyclic Behavior of Shape Memory Alloys during Localized Unstable Mechanical Response

Abstract:

Article Preview

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.
