Sharp knives – high friction
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 […]

Knowing the strength of adhesion
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 […]

A very simple estimate of adhesion with rough surfaces based on a bearing area model
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 […]

Contact mechanics challenge results: a follow up discussion
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. […]
