Digging through 2D densely-packed coarse granular media as a critical phenomenon
Guo-Jie Jason Gao, Fu-Ling Yang, Michael C. Holcomb +1
We create a mechanical digger able to move within 2D densely-packed granular media, in a manner intrinsically different from the existing biomimic diggers. The characteristics of o…
Enhanced flow rate by the concentration mechanism of Tetris particles when discharged from a hopper with an obstacle
Guo-Jie Jason Gao, Fu-Ling Yang, Michael C. Holcomb +1
We apply a holistic 2D Tetris-like model, where particles move based on prescribed rules, to investigate the flow rate enhancement from a hopper. This phenomenon was originally rep…
Studying the Kinetics of a Self-propelled Cruiser in 2D Granular Media under Gravity
Guo-Jie J. Gao
We propose a cruiser able to move in a granular medium made of nearly 50-50 bidisperse dissipative particles under gravity. The cruiser has a circular shape with a square indentati…
Incorporating a soft ordered phase into an amorphous configuration enhances its uniform plastic deformation under shear
Guo-Jie J. Gao, Yun-Jiang Wang, Shigenobu Ogata
Amorphous materials of homogeneous structures usually suffer from nonuniform deformation under shear, which can develop into shear localization and eventually destructive shear ban…
Understanding the Local Flow Rate Peak of a Hopper Discharging Discs through an Obstacle Using a Tetris-like Model
Guo-Jie J. Gao, Jerzy Blawzdziewicz, Michael C. Holcomb +1
Placing a round obstacle above the orifice of a flat hopper discharging uniform frictional discs has been experimentally and numerically shown in the literature to create a local p…
A Tetris-like Model Showing a Universal Enhanced Flow Rate of a Hopper Discharging Hard Discs Through an Adjustable Inclusion
Guo-Jie Jason Gao
In the literature, placing an inclusion near the orifice of a hopper, containing disc particles, has been experimentally and numerically reported to locally enhance the gravity-dri…
