Abstract :
To assist in the design of a compliant vascular graft, a constitutive equation predicting the biomechanical properties of healthy coronary arteries was determined. An experimental design in the physiological range of force and pressure was used to improve data collection. An exceptional fit to the data resulted from using a complementary energy formulation of the constitutive equation. The functional form of the constitutive equation was adapted from the literature
