Development and Calibration of a Segmented Variable-Diameter Flexible Discrete Element Model of Green Foxtail Stems for Orchard Mowing Simulations
Green foxtail (Setaria viridis) is a common orchard weed, but discrete element simulations of mowing operations lack geometric, contact, and flexible-connection parameters for its stems. This study measured the geometry and physical and contact properties of post-mowing regrowth stems and developed a segmented, variabl...
