This document summarizes a simulation of the thermomechanical behavior of shape memory alloys (smas) using comsol multiphysics. it describes modeling a fixed nitinol beam and simulating its shape memory effect and recovery behavior through resistive heating. This constitutive model is temperature dependent and can be used to reasonably capture the typical features of smas during tensile compressive cyclic tests, which include the pseudo elasticity at higher temperatures as well as the shape memory effect at lower temperatures. Modelling fracture behavior of the shape memory alloy (sma) that interacts with martensitic transformation and the associated elastocaloric effect (ece) still remains challenging. herein, a thermo mechanically coupled phase filed fracture model considering elastocaloric effect of sma is proposed to simulate the cracking process coupled with the non isothermal martensitic transformation and the. In the present work we propose a new thermomechanically coupled material model for shape memory alloys (sma) which describes two important phenomena typical for the material behaviour of shape memory alloys: pseudoelasticity as well as the shape memory effect. This paper provides an overview of the mechanical properties and cyclic behavior of various compositions of shape memory alloys (smas) and the factors that affect their responses.
