Abstract
Abstract A three-dimensional finite element model of the carotid artery bifurcation was constructed to determine the effects of prestrain on the stress field. The model takes into account the variation of the thickness along the bifurcation and the material is considered to be hyperelastic, incompressible, homogenous and isotropic. The results demonstrate that when prestrain is taken into account the distribution of principal stress along the inner wall and the circumferential stress throughout the wall is much more uniform than in a model without prestrain. The differences are most significant at the apex.
