A theoretical background to the Hertz contact theory can be found here. Line Contact (Cylindrical contact) In case of two cylinders in contact (with radii ), as shown in Fig. 1, the Hertzian radius of […]

Predicting the size of wear particles

21.11.2016

A wear process results in the generation of particles, of various size, shape, color and chemical composition. The reported size of wear particles varies from mm scale, which is typically attributed to severe wear, to [...]
Tribology and the Human Evolution

12.08.2019

Tribology, not a common household word, is the science of wear, friction, and lubrication, studying how interacting surfaces behave in relative motion. Tribology does not work in isolation but affects a multitude of other fields [...]
Rare earth oxides make water-repellent surfaces that last

11.09.2017

Ceramic forms of hydrophobic materials could be far more durable than existing coatings or surface treatments. Water-shedding surfaces that are robust in harsh environments could have broad applications in many industries including energy, water, transportation, [...]
The science of slippery bananas

24.11.2017

They’re yellow. They’re radioactive. And they’re very slippery. Yes, they’re bananas, and we have just found out why they’re so slippery. So yellow … yes we all know that. But radioactive? Well yes, bananas are [...]
Detect stress and fracture using color changing elastomers - mechanochromic sensors
