The Contact-Mechanics Challenge completed In late 2015 we posed the Contact-Mechanics Challenge. This has now been completed and the winner is—the field of tribology. BECAUSE TRIBOLOGY IS THE STUDY OF contacting bodies in relative motion, […]
Diamond coatings are commonly used today to protect tools and machine components that are subjected to high wear, and thus to extend their service life. It is known that rubbing two dry diamond surfaces together […]
Models for the stress-activated growth of tribofilms from ZDDP were modified to include wear. TWO RECENT CUTTING EDGE ARTICLES reported on work that showed the growth rates of tribofilms from ZDDP were accelerated by contact […]
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 […]
