TI - Shape Memory Alloy: from Constitutive Modeling to Finite Element Analysis of Stent Deployment T2 - Computer Modeling in Engineering \& Sciences PY - 2010 VL - 57 IS - 3 SN - 1526-1506 AB - The use of shape memory alloys (SMA) in an increasing number of applications in many fields of engineering, and in particular in biomedical engineering, is leading to a growing interest toward an exhaustive modeling of their macroscopic behavior in order to construct reliable simulation tools for SMA-based devices. In this paper, we review the properties of a robust three-dimensional model able to reproduce both pseudo-elastic and shape-memory effect; then we calibrate the model parameters on experimental data and, finally, we exploit the model to perform the finite element analysis of pseudo-elastic Nitinol stent deployment in a simplified atherosclerotic artery model.
