Inflation tests and modelling of Human Saphenous Veins

Popis výsledku v původním jazyce

Inflation tests of 15 human saphenous veins were conducted to obtain data suitable for multi-axial constitutive modeling at overloading conditions (pressures up to approximately 15 kPa). The data were fitted with a hyperelastic, nonlinear and anisotropicconstitutive model based on the theory of the closed thick-walled tube. It was observed that initial highly deformable behavior in the pressure circumferential stretch response is followed by progressive large strain stiffening, which is in contrast tothe pressure axial stretch response where the stretches remained in the range 0.98 ? 1.03 during the entire pressurization in most cases. The material parameters presented here are suitable for use in simulations describing the adaptation of the autologous vein wall after bypass surgery.
