Mechanical Optimization of Geometry of the System ?Artery-Vascular Graft?
Original language description
A computational model of stress and strain states in an ?overlapped? anastomosis between artery and vascular graft is presented in the paper. This model is loaded by the systolic blood pressure, axial prestretch and accounts residual stresses in the artery as well. Material of both the artery and the graft is modelled as non-linear elastic, homogeneous, isotropic, with large strains. The model geometry corresponds to aorta and some geometric parameters of the anastomosis (length, ratio of diameters) aree varied with the aim to find the geometry which is optimal from the point of view of stresses and strains induced in the anastomosis. The optimization criterion is that the stress distribution in the artery in the anastomosis is similar to that in an artery unaffected by the anastomosis. The results show that the influence of axial prestretch and residual stress on the stress concentration in the anastomosis is substantial and it has to be accounted in the computational model.
