In dry sliding between a given pair of materials under steady conditions, the coefficient of friction may be almost constant. This is the basis for two EMPIRICAL Laws of Sliding Friction, which are often known […]
The Handbook on Contact Mechanics (Handbuch der Kontaktmechanik) co-authored by Honorary Professor of Tomsk Polytechnic University, head of the Department of System Dynamics and Friction Physics at Technical University Berlin, Valentin Popov, a TPU alumnus […]
Trying to slice a tomato into thin slices with a dull knife can get a little scary. The harder the knife must be pressed downward before the skin is broken is directly related to the […]
Here we present an abstract to a paper devoted to the history of eastohydrodynamic theory and his founder – Alexander Mohrenstein-Ertel. This paper discusses in detailes the peculiar biography of the scientist and the early years of the […]
Today, bearing failure due to rolling contact fatigue is generally a rare occurrence, and the final achieved service life of rolling bearings is usually well in excess of the calculated rating life. There are instances, […]
No future without history! A great article on the history of great discoveries in the field of contact mechanics and friction was recently published by Elena Popova and Valentin L. Popov. Here we present the […]
Behaving like particles in a viscous fluid can help bunches of electrons squeeze through a tight space. When many people try to squeeze through a passageway at the same time, it creates a bottleneck that […]
SKF has employed Minimum Quantity Lubrication (MQL) for its own manufacturing processes and has also developed a comprehensive portfolio of MQL solutions through its LubriLean range. While SKF has recorded significant benefits from its introduction […]
From the brain’s responses to cheese aversion to the fluid dynamics of cats, WIRED picks its favourite Ig Nobel Prize winners for 2017 The winners of the 2017 Ig Nobel Prize, the science awards given […]
Ever swallowed a button-battery? And wondered how to get it out? Have no fear, the origami robot is here! That’s right, the Massachusetts Institute of Technology (MIT) has come up with a pill-sized origami robot, which will […]
