Fretting, fretting corrosion and fretting mechanisms

28.10.2018 tribonet

What is fretting? Fretting or fretting wear is a specific wear type which is characterized by low amplitude oscillating sliding between bodies, which are nominally at rest [1] (for example due to vibration, cyclic stresses, […]

Models Predicting When and How Roads Will Deteriorate

27.01.2020

Heriberto Perez, a researcher at the UPV/EHU’s Faculty of Engineering-Bilbao, has developed behavior models able to predict the future deterioration of roads. The models focus on two different aspects, the international roughness index (IRI) and [...]
Elmer: An Open Source Finite Elements Software

29.06.2017

There are nowadays some Open Source Finite Elements packages available online, just to cite some: Calculix, Salome-Meca (with Code Aster), Z88 Aurora, Elmer, etc. The gap between the paid software (Ansys, Comsol, Abaqus, LS-DYNA,…) and the open source packages is still big, [...]
Small flying robots pull objects up to 40 times their weight using adhesion

03.12.2018

Researchers from EPFL and Stanford have developed small drones that can land and then move objects that are 40 times their weight, with the help of powerful winches, gecko adhesives and microspines. A closed door [...]
Slip, No Slip and Cavitation

05.09.2016

Engineering surfaces are heterogeneous and can be slippery or sticky locally depending on surface roughness and chemistry. The variation of surface properties affects the interaction between the wall and lubricant and determines friction. Slip can [...]
Macroscale superlubricity

11.01.2016

Friction rises when bodies come to contact and start relative sliding. This phenomenon occurs in many mechanical systems and it is estimated that over 30% of the fuel in cars is consumed to overcome [...]
