Title: Modeling the fatigue behavior of thermomechanical shape memory alloys: Application to the optimization of biocompatible actuators for cardiac implants.

Subject: The aim of this project is the development of a thermomechanical modeling tool, robust and able to capture the different inelastic mechanisms that occur under cyclic loading in shape memory alloys (phase transformation, martensitic reorientation, plasticity, damage). This tool will be implemented in the finite element program ABAQUS in order to predict the fatigue of actuators for biomedical engineering applications. The developed model will be operated for the prediction and optimization of the fatigue strength of an innovative cardiac assist actuator equipped with SMA biocompatible material (NiTi and TiNb) under non-isothermal, cyclic and multiaxial, non-proportional loading conditions. The cardiac implant is a lamellar system consisting of a superelastic SMA and it has been designed in collaboration with the Nancy School of Surgery.

Starting date: ASAP.
