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

14.10.2019 1,033 Views
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 [...]
Tribometer managing autumn leaf problem on railways worldwide

25.02.2019 1,501 Views
Since the 1800s, railway organizations have been struggling with low adhesion on the rail, especially during the Autumn season also known as the “slippery track season”. In Autumn, leaves fall on the rails and when [...]
Mixed Lubrication: Wear Particles Size and Friction Evolution

10.04.2017 1,479 Views
Wear in tribological contacts results in generation of wear particles of various sizes and shapes and these particles impact the performance of the mechanical devices. These particles may create additional mechanical damage or act as [...]
