SIMULATION OF JSC-1A LUNAR SOIL SIMULANTS WITH NEW ALGORITHMS DEVELOPED FOR REALISTIC SOIL PARTICLE GEOMETRIES

  • Conference paper
Multiscale and Multiphysics Processes in Geomechanics

Part of the book series: Springer Series in Geomechanics and Geoengineering ((SSGG))

Summary

This article reviews novel algorithms for the Discrete Element Method (DEM) with polyhedral particles to greatly improve the efficiency in particle contact detection which is the most time-consuming part of a simulation. The implemented algorithms are used in simulations designed to reproduce experimental tests on angular JSC-1A lunar regolith stimulant particles.
