Outline of Final Research Achievements

In order to establish novel methodology to analyze macroscopic tribological parts in mechanical system, we have developed in the present research project, (1) computational modeling software of realistic structure of the parts, (2) theoretical prediction of local physico-chemical-mechanical properties, (3) theoretical prediction of tribo-measurement and tribo-testing, (4) theoretical prediction of friction or wear properties of practical parts, (5) human interface for the multiscale, multiphysics tribological simulators to promote collaboration with experimental researchers. The availability of the developed system was demonstrated by many collaborations with experimentalists.
