Tip angle dependence for resistive force into dry granular materials at shallow cone penetration
Naoki Iikawa, Hiroaki Katsuragi
In relation to the interaction of the earth's surface with machines and organisms, and its engineering applications, there has been a recent increase in interest in the penetration…
Force Chain Evolution in a Two-Dimensional Granular Packing Compacted by Vertical Tappings
Naoki Iikawa, M. M. Bandi, Hiroaki Katsuragi
We experimentally study the statistics of force-chain evolution in a vertically-tapped two-dimensional granular packing by using photoelastic disks. In this experiment, the tapped…
Sensitivity of Granular Force Chain Orientation to Disorder-induced Metastable Relaxation
N. Iikawa, M. M. Bandi, H. Katsuragi
A two-dimensional system of photoelastic disks subject to vertical tapping against gravity was experimentally monitored from ordered to disordered configurations by varying bidispe…
Structural evolution of a granular pack under manual tapping
Naoki Iikawa, Mahesh M. Band, Hiroaki Katsuragi
We experimentally study a two-dimensional (2D) granular pack of photoelastic disks subject to vertical manual tapping. Using bright and dark field images, we employ gradient-based…
