05.10.2018 F. Xavier Borras

Every second year the EDF-PPRIME Workshop is dedicated to sealing technology. This week the 17th edition of this event was held at the EDF Lab Paris-Saclay focusing on minimizing both leakage and friction of rotary […]

Contact Area Calculation Tutorial: Boundary Element Based Model vs. Asperity Based Model

14.03.2018

In contact mechanics and tribology it is frequently needed to calculate the contact area between rough surfaces to estimate possible slip, friction, electric conductivity, etc. In this tutorial, it will be shown how to perform [...]
Bi-layered materials: graphene - no heat, no friction; h-BN - as strong as diamond.
