Impact of grain properties on the penetration of intruders near a wall into granular matter: a DEM study

TL;DR

This study uses DEM simulations to analyze how variations in grain properties like friction, Young's modulus, and restitution coefficient affect the penetration behavior of an intruder near a wall in granular materials.

Contribution

It introduces a detailed DEM simulation approach to systematically investigate the influence of grain mechanical properties on intruder penetration near a wall.

Findings

Penetration depth varies with grain friction and elasticity.

Mechanical properties significantly influence granular response.

Simulation results align with experimental observations.

Abstract

DEM simulations were used to study the sensitivity of a granular system to the change of the mechanical properties of the grains, applied to the penetration of a cylindrical intruder near a vertical wall. The simulations reproduce a real experimental setup, changing the friction, the Young modulus and the restitution coefficient of the particles.
