Force measurements on an intruder in pre-fluidized sand

ORAL

Abstract

A container filled with sand is fluidized from below, and by slowly turning of the air flow a very loose packing is created. An intruder controlled by a linear motor is connected to a load cell to measure the force it experiences while moving through the bed. By varying several parameters, such as the intruder shape, velocity, and penetration depth, we aim to obtain a better understanding of the behavior of loosely packed granular materials.
