Ex-Vivo Tribological Behavior of Cow Skin

Kussay A Subhi, Andrei Tudor, Emad K Hussein


Friction involving human skin considers one of important role in daily human life. There are several tried to measure the friction in the human skin in the reality, but it’s still difficult due to limited the equipment. In the current study, the cow skin is used to measure the coefficient of friction as a function of angular velocity and different pressure. Moreover, Parameters such as contact area and the tip of indenter depth was measured in the study. The study results showed that the coefficient of friction is decreased when the pressure increased, whereas it’s increased when the angular velocity increased.


Friction skin; twist friction; ex-vivo skin; cow skin.
