Mechanical properties of drying plant roots: Evolution of the longitudinal Young's modulus of chick-pea roots with dessication
Christopher Vautrin, Pascal Kurowski, Patricia Genet +3
Mechanical characterizations of plant roots are of primary importance in geophysics and engineering science for implementing mechanical models for the stability of root reinforced-…
Bending transition in the penetration of a flexible intruder in a 2D dense granular medium
Nicolas Algarra, Panagiotis Karagiannopoulos, Arnaud Lazarus +2
We study the quasi-static penetration of a flexible beam in a two-dimensional dense granular medium lying on an horizontal plate. Rather than a buckling-like behavior we observe a…
Intruder mobility in a vibrated granular packing
Rim Harich, Thierry Darnige, Evelyne Kolb +1
We study experimentally the dynamics of a dense intruder sinking under gravity inside a vibrated 2D granular packing. The surrounding flow patterns are characterized and the fallin…
Unjamming a granular hopper by vibration
A. Janda, D. Maza, A. Garcimartin +3
We present an experimental study of the outflow of a hopper continuously vibrated by a piezoelectric device. Outpouring of grains can be achieved for apertures much below the usual…
Reorganization of a 2D disordered granular medium due to a small local cyclic perturbation
E. Kolb, C. Goldenberg, S. Inagaki +1
We measure experimentally the rearrangements due to a small localized cyclic displacement applied to a packing of rigid grains under gravity in a 2D geometry. We analyze the evolut…
Reorganization of a dense granular assembly: the `unjamming response function'
E. Kolb, J. Cviklinski, J. Lanuza +2
We investigate the mechanical properties of a static dense granular assembly in response to a local forcing. To this end, a small cyclic displacement is applied on a grain in the b…
