Elmer: An Open Source Finite Elements Software

29.06.2017 F. Xavier Borras 1,412 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 196 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 481 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 296 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 […]

Ab Initio Analysis of Carbon Film Lubricity

16.05.2016 Aydar Akchurin 129 Views
Carbon-based nanomaterials, coatings and films attracted a great attention due to proved possibility to achieve lowest friction and wear without environmental pollution. However, frequently, the state of the low friction is strictly related to the […]

Hysteresis in Friction of Graphene

02.05.2016 Aydar Akchurin 349 Views
Friction is a result of complex interaction of physical, chemical and mechanical forces at the sliding interface. Due to mentioned complexity, truly predictive models of friction are yet to be developed. As a result of […]
