Abstract: Highlights: [•] 3D DEM was applied to analysis of cutting resistance by a narrow blade in dry sand. [•] Effects of elemental model soil created by combining unit spheres were observed. [•] The six studied shapes showed similar horizontal and vertical cutting resistance. [ABSTRACT FROM AUTHOR]
