Joint wear simulation 51
better experimental data and greater collaboration to resolve the outstand-
ing issues.
It should be noted by the reader that these ‘advanced’ second- and
third-generation models apply speci cally to polymer wear; for many
years, some researchers have argued that the relationship is non-linear
for polymers (see Rhee, 1970). Researchers investigating wear in other
biomaterials, for example, metal-on-metal implants, currently still regard
the basic rst-generation Archard model as the state-of-the-art standard
for numerical modelling simulation (see for example, Cosmi et al ., 2006;
Fialho et al. , 2007; Ali and Mao, 2012).
The most important thing for any investigator to realise when working
with wear simulators ...
