Dem simulations on gate loads and bin storage characteristics before discharge

Jiahe Shen et al.

Summary: This study extended the research by using the Discrete Element Method to describe the gate loads in conjunction with the bin storage characteristics. It was found that a passive stress state may be partially ignited due to the deformation of bulk solids and gate supports before discharge.
