Abstract

This work discusses the importance of adequate modelling of mechanical properties of zinc dialkyldithophosphate (ZDDP) tribofilms, namely elastic modulus and hardness, for use in continuum mechanics computational simulations. A review of previous modelling efforts is conducted, and novel methods are proposed. The novel approaches are examined in contact mechanics simulations involving ZDDP tribofilms on steel surfaces. A comparison between the new methods and some previous modelling attempts is presented. The new elastic modulus and hardness and plastic deformation models performed well in simulations.

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
