“…The p-2 curves for the arteries are concave upward as expected. 27,30 The slope gradually increases with stretch ratio and becomes exceptionally high when 2 reaches a value of about 1.42 ± 0.12 (or when pressure exceeds 120 mmHg). The underlying structure of the arterial wall must be responsible for the noted mechanical behavior.…”

“…[22][23][24][25][26] The work of Hayashi et al and that of one of the present authors (V.A.K.) and his associates [28][29][30] shed some light on the properties of human blood vessels; however, more insight is needed on the structure and properties of arteries before small diameter grafts with maximum potential success can be engineered.…”

“…Since their testing protocol and reporting method are different, we are not able to make a direct comparison with shear stress and amount of shear values that we have obtained. To identify the shear modulus (ratio between shear stress and amount of shear) inflation-extension–torsion tests were performed on human common carotid arteries (Kas'yanov et al, 1978), on rat thoracic aortas (Deng et al, 1994), and on porcine coronary arteries (Lu et al, 2003). All these studies showed that the shear modulus was constant with changing twist angle while the longitudinal stretch and the inner pressure were kept constant at chosen physiological levels.…”

“…All these studies showed that the shear modulus was constant with changing twist angle while the longitudinal stretch and the inner pressure were kept constant at chosen physiological levels. Furthermore, the shear modulus was different for different values of longitudinal stretch and applied internal pressure (Kas'yanov et al, 1978; Lu et al, 2003), and the relation became nonlinear at pressure levels higher than 120 mmHg (Kas'yanov et al, 1978). The maximum twist angle applied in these studies was 25° under a mixed loading state.…”

“…We set m ¼ 1:2 Â 10 6 dyn=cm 2 based on the experimental results of Kasyanov et al (1978). For the bulk modulus, which is used as a volumetric penalty parameter for enforcing the quasi-incompressibility constraint, a suitable value for arteries is K ¼ 10 9 dyn=cm 2 (Carew et al, 1968).…”
