... research for “pressure-corrected” metrics of stiffness. As should be clear from the preceding text, however, arterial mechanics is highly nonlinear and fully capturing it requires complex constitutive relations with many parameters, with value(s) of stiffness always dependent on the level of stress...

.... However, the true value of Poisson's ratio for liver parenchyma is lacking in the literature and should be addressed in future studies. Finally, the initial state of stress of the non-pressurized samples of isolated liver parenchyma tested in the current study is likely different from the initial...

... artery was tested after storage for 1–28 days in physiologic saline at 4°C. There were no significant effects of storage time on the arterial diameter or force at each pressure, but there were significant effects on the stretch ratio and stress at each pressure. The significant effects on the stretch...

... not be adequate as the geometry of the cerebral ventricles is unique. In this study, a three-dimensional (3D) finite element model of the cerebral ventricles during hydrocephalus is presented. Results from this model show that during hydrocephalus, the periventricular regions experience the highest stress...

The presence of a stent can subject the artery to abnormally high stresses that can trigger adverse biologic responses culminating in restenosis. The primary aim of this investigation was to investigate the effects of varying stent “design...
