Modelling of stress-strain states in arteries as a pre-requisite for damage prediction
Original language description
Damage to arteries can be caused by a number of different factors ranging from the influence of mechanical load of arterial walls on endothelial cells and, consequently, on the genesis of atheromatous plaques on the inner surface of the walls, to a global tissue rupture. To predict these states, it is necessary to know not only the limit conditions and limit values but also the most credible stress and strain states. These states were solved using FEA (ANSYS program system), namely in an intact artery aand in various geometric shapes of joints (anastomoses) with a vascular graft. The computational model used the axisymmetrical geometry with up to two different homogeneous coaxial layers in the artery wall. The material was supposed to be non-linear elastic, isotropic, nearly incompressible, showing finite displacements and strains under physiologic load. The model considered three major load factors: blood pressure, axial prestretch and residual stresses. The influence of axial prestre
