... such as stress and stiffness can be determined by solving the associated initial-boundary value problem. Data on indentation force ( f ) and depth ( δ ) are often interpreted using a classical 19th century solution by Hertz for the localized indentation of a semi-infinite half-space that exhibits...

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 state of stress of the liver in vivo due to blood pressure and contact with surrounding tissues. However...

... 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...
