Constitutive Equations for Human Saphenous Vein Coronary Artery Bypass Graft

Popis výsledku v původním jazyce

The purpose of this study is to find a constitutive model for CABG tissue. A sample of the CABG obtained within an autopsy underwent an inflation-extension test. Displacements were recorded by CCD cameras and subsequently evaluated by digital image correlation. Pressure - radius and axial force - elongation data were used to fit material model. The tissue was modeled as one layered composite reinforced by two families of helical fibers. The material is assumed to be locally orthotropic, nonlinear, incompressible and hyperelastic. Material parameters are estimated for two strain energy functions (SEF). The first is classical exponential. The second SEF is logarithmic which allows interpretation by means of limiting (finite) strain extensibility. Presented material parameters are estimated using radial and axial equilibrium equation in a thick-walled tube. Both material models fit experimental data successfully.
