Concerns surrounding the sustainability of our environment continue to receive close attention around the world. Global citizens look for new technology to provide them with improved creature comforts while, at the same time, technology that […]

Next-generation composites may monitor their own structural health

21.01.2019 330 Views

Carbon fiber composites—lightweight and strong—are great structural materials for automobiles, aircraft and other transportation vehicles. They consist of a polymer matrix, such as epoxy, into which reinforcing carbon fibers have been embedded. Because of differences [...]
The Mechanism of Glycerol Superlubricity

09.05.2016 1,126 Views

Glycerol is a highly viscous liquid, generating friction coefficient of 0.1 and up for bearing steels in boundary lubrication. In full film EHL, pure glycerol generates high friction as well and therefore is rarely used [...]
So, what is it, superlubricity?

27.01.2016 1,477 Views

From the first friction quantitative experiments by Leonardo da Vinci (1452-1519) and most notably from our everyday life experience, it is known that there is an inevitable force opposing to the initiation of motion of [...]
Contact Area vs. Load: Simple Scaling Laws

04.07.2016 1,572 Views

“God made the bulk; surfaces were invented by the devil”, a Nobel prize winning physicist Wolfgang Ernst Pauli said. In tribology, as in many other sciences, surface features (asperities, roughness) play an important role. In [...]
Anyone is up for challenge?

08.01.2016 192 Views

Society of tribology and lubrication engineers announced Contact Mechanics Challenge. Dr. Martin Müser initiated a competition in calculation of a real contact area. He has already results of his own calculation and challenges other groups [...]
