Morphology-resolved stress contributions in sheared wet granular materials
Ahmad Awdi, Camille Chateau, Coumba Niang +3
Three-dimensional X-ray microtomography, coupled to rheometric measurements, enables a morphology-resolved reconstruction of capillary stresses at the grain scale in unsaturated we…
Linear poroelastic response of thin permeable gel films
Caroline Kopecz-Muller, Joshua D Mcgraw, Thomas Salez
When a hydrophilic and deformable porous material is immersed in a bath, it may absorb the solvent and expand by several times its volume, thus forming a highly soft and porous hyd…
The vibrational spectrum of vitreous silica: rigorous decomposition via recursive orthogonal splitting analysis
Nikita S Shcheblanov, Anaël Lemaître
Our understanding of vibrations in solids currently rests on concepts and techniques designed for crystals and explicitly relying on periodicity, hence inapplicable to amorphous ma…
Anisotropic truncation for turbulent transport and zonal flows in the Hasegawa-Wakatani system
Pierre L. Guillon, Robin Angles, Yanick Sarazin +1
Reduced models based on an anisotropic truncation of the Fourier space, retaining only a few poloidal wave-numbers while keeping the full radial resolution, are developed and first…
Predicting cement microstructure and mechanical properties in hydrating cement paste with a Phase-Field model
Alexandre Sac-Morane, Katerina Ioannidou, Manolis Veveakis +1
Predicting the evolving microstructure of hydrating cement is essential for understanding and modeling its mechanical property development. Physics-based continuum approaches offer…
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…
