Wear-mechanism modelling [PDF]
, 1993 Goals of the program are to calculate the surface temperatures in dry sliding, develop a soft wear tester for ceramics, survey the wear mechanisms in brittle solids, and couple the temperature calculations with models to give wear maps for brittle solids. (DLC)

Bionic design perspectives based on the formation mechanism of dental anti-wear function
Biosurface and Biotribology, 2017 Human teeth are the important masticatory organ and therefore are subjected to friction and wear everyday. Both the loading condition and the environment are relatively complex in the mouth, however, normally human teeth can serve in mouth all their time

Dynamics Analysis of Spatial Parallel Mechanism with Irregular Spherical Joint Clearance
Shock and Vibration, 2019 Clearances caused by machining accuracy and assembly requirements are regular, but they will be irregular due to the wear of the kinematic pairs. At present, there are few studies on wear of space kinematic pairs.

Wear mode and wear mechanism of retrieved acetabular cups [PDF]
International Orthopaedics, 2003 Nineteen ultra-high-molecular-weighted polyethylene (UHMWPE) cups were retrieved at revision surgery. The implant period was on average 9.9 (0.25-20.7) years. The cups were classified into the high-wear group (wear rate above 140 mm(3)/year), intermediate-wear group (wear rate 80-140 mm(3)/year) and low-wear group (wear rate below 80 mm(3)/year).
