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

Lee, S. J. / Hashash, Y. M. A. / Wilkinson, R. A. / Agui, J. H.

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.
