slipportion
Slipportion is a dimensionless parameter used in tribology and contact mechanics to quantify the fraction of relative motion at a contact interface that is accommodated by slip along the interface, as opposed to sticking or elastic deformation elsewhere. It provides a concise measure of how much sliding occurs between contacting surfaces under a given load and speed.
Definition and calculation: Slipportion is commonly defined as the ratio of slip displacement to the total
Measurement and interpretation: Methods for determining slipportion include digital image correlation, high-speed imaging of the contact
Applications: Slipportion is used in the design and evaluation of bearings, seals, and microelectromechanical systems, as
