Abstract

This paper present a thermo-mechanical one dimensional constitutive model based on the use of strain and temperature as control variables and able to reproduce the basic responses of shape memory material such as super elasticity, shape memory behavior, pseudoelasticity, single variant martensite reorientation process. The model time integration is performed and a robust algorithm for solution of the time discrete model is addressed together with algorithmically consistent tangent. The model is implemented in NITINOL wire (Ni-Ti-6% Cu) which is used to simulate the above mentioned responses. The Thermomechanical response at different temperatures compare well with experimental and numerical results.
