Tribology Wiki


Tribology Wikipedia has the same goal as the well-known Wikipedia: share knowledge from around the globe and create an encyclopedia accessible to anyone. Of course, Tribology Wiki has an emphasis in Tribology! Everyone is invited to read, write, edit and share Wikis. Please contact us via email if you would like to contribute an article or if you have any suggestions!

Worn Steel Disk

Archard Wear Equation

The importance of wear losses leads to considerable effort in establishing theories and predictive models of wear. Meng and Ludema  [1] have identified 182 equations for different types of wear. Among them were empirical relations, […]

Elastic Deformation

Elastic Deformation

Definition Elastic deformation is a change of the shape of the body as a reaction to applied stress. This deformation is only temporary and once the stress is released, the undeformed shape of the body […]

tribometer

Tribometers

Tribometers are the devices used to analyze and characterize tribological systems. The most common direct measurement is the measurement of friction coefficient (and shear strength). During the post processing stage other quantities can be measured, […]

Friction Coefficient

Coefficient of Friction

Friction is a force resisting relative motion and may occur at the interface between the bodies, but may also occur within the bodies. The concept of friction coefficient was first formulated by Leonardo da Vinci […]

Fatigue Surface Crack

Rolling Contact Fatigue

Rolling-contact fatigue (RCF) is defined as a failure or material removal driven by crack propagation caused by the near-surface alternating stress field.  It is typically considered that if a bearing is properly mounted, aligned, lubricated, […]
