The Thermal Unbalance Effect Induced by a Journal Bearing in Rigid and Flexible Rotors: Experimental Analysis

Thibaud Plantegenet, Mihai Arghir, Mohamed-Amine Hassini +1

The present work presents the experimental analyses of a rigid (short) and a flexible (long) rotor subject to thermal unbalance effects. The rotors are supported by a ball bearing…

The influence of grain crushing and pore collapse on the formation of faults

N. A. Collins-Craft, I. Stefanou, J. Sulem +1

During an earthquake, slip occurs in a localised shear zone that features a heavily granulated fault core that can be characterised as a shear band. We study the formation of this…

How to introduce an initial crack in phase field simulations to accurately predict the linear elastic fracture propagation threshold?

Flavien Loiseau, Veronique Lazarus

Variational phase field fracture models are now widely used to simulate crack propagation in structures. A critical aspect of these simulations is the correct determination of the…

A mixing length model for arbitrary geometry: the case of parallel flows

Vincent Labarre, Christophe Josserand, Martine Le Berre +3

We present a phenomenological model for the mixing length used in turbulence models. It has the advantage of naturally accounting for the object's geometry while satisfying the sta…

Reinforcement learning-based adaptive time-integration for nonsmooth dynamics

David Michael Riley, Alexandros Stathas, Diego Gutiérrez-Oribio +1

Numerical time integration is fundamental to the simulation of initial and boundary value problems. Traditionally, time integration schemes require adaptive time-stepping to ensure…
