Richard M. Stallman, founder and president of the Free Software Foundation and founding father of the GNU Project, has a long been repeating “say GNU, not Linux” although he has not had much success. In the same sense, from this corner […]

Adhesive wear model: particle by particle

23.07.2017 tribonet 498 Views
10.07.17 – An EPFL study has deepened our understanding of the fine particles produced by adhesive wear. This breakthrough could lead to cost savings and environmental benefits. Adhesive wear occurs when two surfaces – such […]

Elmer: An Open Source Finite Elements Software

29.06.2017 F. Xavier Borras 1239 Views
There are nowadays some Open Source Finite Elements packages available online, just to cite some: Calculix, Salome-Meca (with Code Aster), Z88 Aurora, Elmer, etc. The gap between the paid software (Ansys, Comsol, Abaqus, LS-DYNA,…) and the open source packages is still big, […]

Stress Assisted Tribofilm Growth: A New Model

18.04.2017 tribonet 412 Views
Under extreme conditions the lubricant film fails to separate the rubbing surfaces and solid-to-solid contact occurs. To prevent excessive wear of the base materials anti-wear additives are used in these cases. The additives create a […]

Predicting the size of wear particles

21.11.2016 tribonet 723 Views
A wear process results in the generation of particles, of various size, shape, color and chemical composition. The reported size of wear particles varies from mm scale, which is typically attributed to severe wear, to […]

Slip, No Slip and Cavitation

05.09.2016 Aydar Akchurin 1619 Views
Engineering surfaces are heterogeneous and can be slippery or sticky locally depending on surface roughness and chemistry. The variation of surface properties affects the interaction between the wall and lubricant and determines friction. Slip can […]
