A device for studying elementary plasticity fluctuations in granular media
Ambroise Mathey, Mickaël Le Fur, Patrick Chasle +2
In this manuscript, we describe a scientific device specifically designed for the study of the plasticity fluctuations preceding the fracture of granular media. Biaxial tests on mo…
Spatial repartition of local plastic processes in different creep regimes in a granular material
A Pons, T Darnige, Jérôme Crassous +2
Granular packings under constant shear stress display below the Coulomb limit, a logarithmic creep dynamics. However the addition of small stress modulations induces a linear creep…
Mechanical fluctuations suppress the threshold of soft-glassy solids : the secular drift scenario
Adeline Pons, Axelle Amon, Thierry Darnige +2
We propose a dynamical mechanism leading to the fluidization of soft-glassy amorphous mate-rial driven below the yield-stress by external mechanical fluctuations. The model is base…
