4. Digital tribology today

Over the last decade, digital tribology has undergone considerable development. It has taken advantage of the numerous numerical developments in the world of contact mechanics, adapting them to its own needs and becoming an indispensable tool for studying contact problems.

The need to better understand the phenomena involved means that today we need to be able to take into account ever finer models. Models are no longer based on a single, purely mechanical scale, but involve several scales and integrate different physical phenomena.
