Biological materials have complex mechanical properties that are difficult to reproduce using synthetic materials. An international team of researchers, including Dr. Andrey Dobrynin, a professor in The University of Akron’s College of Polymer Science and […]
EU-funded researchers developed a novel process for surface hardening of stainless steel that ensures high hardness with extraordinary corrosion and fatigue resistance properties. Stainless steel is the material of choice in various industries where corrosion […]
Despite the numerous advances in solar cells, one thing remains constant: cloudy, rainy conditions put a damper on the amount of electricity created. Now researchers reporting in the journal ACS Nano have developed hybrid solar […]
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 […]
In contact mechanics and tribology it is frequently needed to calculate the contact area between rough surfaces to estimate possible slip, friction, electric conductivity, etc. In this tutorial, it will be shown how to perform […]
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 […]
How can flies walk on the window glass upside down? How can geckos climb walls and trees? It looks like a simple question, but it is hard to answer. The secret is that flies and geckos, and many other living […]
Here we present an abstract to the paper addressing a simplified model for adhesion between hard rough solids. Abstract In the present note, we suggest a single-line equation estimate for adhesion between elastic (hard) rough […]
In 2015 Prof. Martin Müser of Saarland University in Saarbrücken, Germany initiated a contact mechanics challenge with a goal to provide tribologists with benchmarks to decide which method is the most appropriate for a particular problem. […]
