Home - Group 'Tribology and Interface Mechanics (TMI)'






Objectives :
Ensure the separation of the solids when moving
Control the friction and wear in diverse - even opposite - cases

Method :
Study of the interface between the contacting bodies


Why ?
To avoid the dysfunction of the mechanisms,
To control the wear of the contacting parts,
To limit the energy dissipation,
To preserve
  Worn knee prothesis  Cracked brake disk (truck) 
  Failure of the lubricant  Worn rail (with the new rail profile 


       Approach :
Reproduce the phenomena (pilot experiments)
Numerical simulation
Observation, measurement
and characterization (on site, tribometer, test bench...)
  Result of a numerical simulation  Surface of a damaged rail  
  Study of a liquid bridge  Interferogram
