Simulation of Uniaxial Compression for Flexible Fibers of Wheat Straw Using the Discrete Element Method

Abstract: HighlightsSimulation of uniaxial compression was performed with flexible fibers modeled in DEM.Bond-specific DEM parameters were found to be sensitive in uniaxial compression.A calibration technique that is not plunger-dependent is shown and validated.Abstract. To accurately simulate a discrete element method (DEM) model, the material properties must be calibrated to reproduce bulk material behavior. In this study, a method was developed to calibrate DEM parameters for bulk fibrous materials using uniaxial c… Show more

“…With the assistance of a parallel bonding model in DEM and the calibration of bonding parameters under Hertz–Mindlin 9 , proposed a study to simulate the bending behaviour of flexible wheat straw and developed a switch grass model using the uniaxial compression model 19 . A systematic methodology was employed, as outlined by 7 in the bending test and cantilever test, followed by the uniaxial compression test as per 20 .…”
