In this contribution an approach for the fiber reorientation in three‐dimensional arterial walls is presented. In detail the load‐bearing capacity of the tissue is increased by re orienting the fibers with respect to the principal stresses, cf. [1]. The improved fiber reorientation algorithm is combined with the polyconvex nonlinear anisotropic material model presented in [3]. The results of a three‐dimensional finite element simulation, where the reorientation approach is applied to a short segment of a patient‐specific arterial geometry, are presented.
