 The analysis goals are to calculate the stress-strain fields that develops during the various stages of stent deployment into a blood vessel and to calculate the fatigue behavior and safety factor of the stent under in vivo conditions. The FE model of the stent contained the smallest repeating pattern of the struts under appropriate symmetry conditions. […]
