Abstract
NiTi shape memory alloys start to be widely used in mechatronic systems. In this article, theoretical elastic constants of austenitic and martensitic phases of perfect NiTi crystals and martensitic crystals containing twins in compound twinning mode are presented as computed by using first principles methods. The comparison of elastic constants of the twinned NiTi martensite with those for perfect crystals helps us to understand the transition from elastic to pseudoplastic behavior of NiTi alloys. The results indicate that the elastic response is not influenced by the presence of the twins.
