A Multi-Scale Investigation to Predict the Dynamic Instabilities Induced by Frictional Contact

F Maaboudallah, N Atalla - Lubricants, 2023 - mdpi.com
We propose a new variational formulation to model and predict friction-induced vibrations.
The multi-scale computational framework exploits the results of (i) the roughness …
