Comparing non-local granular fluid continuum models for silo discharge: Toward clogging prediction
Y. Zhou, Y. Wang, M. Li +1
Non-local constitutive theories have received increasing attention in continuum descriptions of granular flows. However, these models have not been systematically compared for silo…
Evolution of the contact between rough viscoelastic solids after decreasing loads: memory erasure and monotonic increase
Zichen Li, Renald Brenner, Lucas Frérot
The real area of contact governs, in part, the magnitude of the friction force, yet its time evolution in rough viscoelastic interfaces remains incompletely understood. In experime…
Classifying soft elastic lattices using higher-order homogenization
Basile Audoly, Claire Lestringant, Hussein Nassar
We propose a methodology for the homogenization of periodic elastic lattices that covers the case of unstable lattices, having affine (macroscopic) or periodic (microscopic) mechan…
Deformation of hydrogel during freezing
Lila Séguy, Axel Huerre, Suzie Protière
We conducted experiments to directionally freeze agar hydrogel drops with different polymer concentrations, on a copper substrate maintained at low temperature. Unlike the water dr…
Asymptotic, second-order homogenization of linear elastic beam networks
Yang Ye, Basile Audoly, Claire Lestringant
We propose a general approach to the higher-order homogenization of discrete elastic networks made up of linear elastic beams or springs in dimension 2 or 3. The network may be nea…
Elastic instability behind brittle fracture
D. Riccobelli, P. Ciarletta, G. Vitale +2
We argue that nucleation of brittle cracks in initially flawless soft elastic solids is preceded by a nonlinear elastic instability, which cannot be captured without accounting for…
