Cerebral aneurysms can cause diseases such as subarachnoid hemorrhage when they rupture, so it is important to treat them before they rupture. One treatment device for cerebral aneurysms is the Flow-diverter Stent (FDS), but treatment with FDS requires that the FDS be placed in the appropriate position. One method for predicting the effectiveness of FDS involves creating a cerebral aneurysm from DICOM images and performing FDS placement simulations using the finite element method. In this study, we replicated stents with varying friction coefficients and compared the experimental values of the mechanical behavior of the stents verified in previous papers to identify the friction coefficients for the created model. The results of this study showed that no significant influence of the dynamic friction coefficient was observed, but the static friction coefficient was determined to be approximately 0.2–0.3. Through this study, we were able to identify the friction characteristics of the finite element stent model created, which is considered an important factor for predicting the effectiveness of FDS using the finite element method in the future.
