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 […]
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 […]
There’s something about the moan and wail of a good gut-bucket slide guitar riff that can grab you by the innards and not let go. Any tribologist worth his salt is likely to have another […]
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, […]
Summary Taking a statistical approach to the condition monitoring of wind turbines is helping wind energy operators control their operation and maintenance costs. SKF is using its wealth of knowledge and considerable database about thousands […]
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 […]
Wear in tribological contacts results in generation of wear particles of various sizes and shapes and these particles impact the performance of the mechanical devices. These particles may create additional mechanical damage or act as […]
The requirement for greater energy efficiency in engineering systems has led to a general reduction in lubricant viscosity, which means that an increasing number of engineering components operate under boundary lubrication conditions. As a result, […]
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 […]
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 […]
