Finite element analysis of Palmaz-Schatz stent and express stent using three dimensional models

摘要

The paper reviews the Finite Element Analysis (FEA) on three dimensional models of two different types of stents namely Palmaz-Schatz stent and Express stent. The simulations are performed for 2 cases: first is stents made of 316 LN Stainless Steel material and L605 Cobalt Chromium alloy. FEA analysis is a computerised method that numerical uses Numerical techniques to analyse the behaviour of a Stent. A CAD model of the stents is generated that are divided into small and simpler elements known as Finite Elements. The stent CAD model is meshed, then it undergoes simulation process. The results are been Post-processed. From finite element analysis of stents the post processed results of Von Mises Stress were studied for strength analysis.
