dc.description.abstract It is important for cardiologist to understand the stresses and strains the stent experiences during deployment . We created a 3 -D model of the coiled stent which is exported into ANSYS creating the finite element model . The stent material is Poly -L -Lactic Acid (PLLA ) fiber with a Young's modulus of 7043 (MPa ) and a Poisson's ratio of 0 .35 . A nonlinear material analysis simulates the material behavior through plastic deformation during expansion from 1 (atm ) to 14 (atm ) . The von Mises stresses , principal stresses , and principal strains are analyzed to determine the yielding of the PLLA fiber . Also , the effect of different material properties including Young's modulus , yield stress , yield strain is examined for the baseline case and three additional cases with Young's modulus of 4701 , 3189 , and 2266 (MPa ) . The axial displacement values are increased to see any effect on the maximum shear stresses . Finally , verification testing is performed to compare the experimental results to the simulation results . en_US
