The computional analysis of those materials is demonstrated on a segment of an artery. StijJeners in the axial direction create a composite structure which models orthotropic nonlinear material properties. The axial stijJening is modeled by finite elements, by a modification of the wall structure and by the modification of material properties of the stijJeners. This composite model of the arterial provides an idea about the influence of orthotropic properties on its deformation and stress state. The results show a disagreement with a model using the homogeneous isotropic nonlinear elastic material behaviour. The explanation may be found in an invalidity of the super position principle under large displacements of the non linear elastic material
