The mechanical behavior of arterial walls in the physiological range can be described by anisotropic, hyperelastic elasticity models. Diferent models can be considered. Each of them is represented by a polyconvex strain energy function in order to guarantee the existence of minimizers. Discretization of these three dimensional models by the finite element method usually results in a large number of equations which requires eficient robust and parallel scalable solvers. Dual-primal FETI methods are
among the most severely tested domain decomposition methods for the solution of partial diferential equations on parallel computers. A computational framework using a Newton-Krylov-FETI approach for the solution of the discretized arterial wall models will be discussed and numerical results will be presented.
