Finite Element Analysis of Nitinol stent (application in abdominal aorta) / Aridani Mat Zin

Stent is a small cylindrical device that is designed to keep open a blocked or narrowing blood vessels or other passageway in a human body. However there are several complications after the insertion of the stent and some of them are related to the design of the stent. Super elastic Nitinol is a com...
