Abstract

Shape memory alloy (SMA) have presented excellent ability for applications in many domains, especially in medical and biomedical applications). Based on the framework of general inelasticity, a 3D super-elastic SMA constitutive model is proposed and implemented successfully into the finite element codes (e.g. ANSYS). The validity of such implementation was finally presented and compared with experimental results of super-elastic NiTi alloy taken from the literature. Finally, this model is used to analyze the stress distribution of a bolted joint for osteopathic medicine.
