Boundary Lubrication

15.03.2020 James Ewen, PhD

What is Boundary Lubrication? Boundary lubrication describes situations where the applied load is primarily supported by contacting solid asperities, rather than a liquid lubricant. The boundary lubrication regime acts when the lambda ratio (the ratio […]

A two-body abrasive wear model as a contact-induced fracture process

14.10.2019

A recent work by the researchers from Leibniz University Hannover presents a 3-D framework for simulation of contact-driven-fracture processes (like abrasive wear) in filled elastomers. Modeling of material removal processes, like wear, to this day [...]
The Evolution of Rotary Lip Seals

03.07.2018

In the world of sealing, it seems as though there are as many varieties of pump applications as there are sealing solutions. Many breakthroughs in technology have aided the evolution from braided packing to advanced mechanical seals, [...]
Creating a Robo-Dog Army: Tribological Aspects

02.09.2019

Recently Boston Dynamics’ released a video of a robo-dog army pulling a truck down the road. The future is here. For now it looks like the good old Terminator I movie. But I guess we [...]
An Open Access Tribology journal is launched

14.05.2018

Chief Editors Professor Valentin Popov and Dr. Roman Pohrt will foster multidisciplinary knowledge exchanges on tribology — a subject integral to any system with moving parts. Tribology — the study of friction and wear — [...]
Switchable Friction on Graphene

15.08.2016

Graphene is a unique material in many aspects and has recently been applied in various ways. In tribology, it has been shown to lead to a superlubricity – an ultra low friction state. In laboratory [...]
