Adhesion of Rough Solids
Computational Tribology

Some open problems in adhesion (of rough surfaces)

30.01.2018 tribonet 358 Views

By M.Ciavarella, A. Papangelo. Politecnico di BARI, Italy. Adhesion for ‘‘soft’’ bodies shows instabilities like in the simple case of a single sinusoid even in the so called JKR regime (Johnson 1995) which leads to […]

Tribology Simulator

Contact Area vs. Load: Simple Scaling Laws

04.07.2016 Aydar Akchurin 262 Views

“God made the bulk; surfaces were invented by the devil”, a Nobel prize winning physicist Wolfgang Ernst Pauli said. In tribology, as in many other sciences, surface features (asperities, roughness) play an important role. In […]
