Plant root growth against a mechanical obstacle: The early growth response of a maize root facing an axial resistance agrees with the Lockhart model
Manon Quiros, Marie-Béatrice Bogeat-Triboulot, Etienne Couturier +1
Plant root growth is dramatically reduced in compacted soils, affecting the growth of the whole plant. Through a model experiment coupling force and kinematics measurements, we pro…
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…
