Abstract

In order to improve the blood flow in artherosclerotic arteries an extension of the lumen is essential. An often used method of treatment is the balloon-angioplasty, whose success requires the knowledge of the mechanics of arterial walls. Thus the numerical simulation provides a method to analyse the deformation behavior of the arterial wall and its constituents under the loading by a ballon-angioplasty. The necessary 3D-discretizations by finite elements results in large systems of equations, therefore, a parallel algorithm using FETI-DP is applied to solve the equilibrium problem.
