title = "A Model for Trap Door Flow from a Deep Container",
abstract = "Computational simulations of trap door flow in cohesive frictional, materials are presented. We focus on flows where the extraction volume is generated by dilatancy. The dilatancy is caused by micro-cracking associated with the loss of cohesion at the onset of flow and/or the transition of the granulate into a more mobile, more loose packing order. The material behavior is modelled as a non-Newtonian fluid including rigid plastic behavior as a limit case. A rate dependent cohesion term considers the fluid like behavior if collisions dominate the intergranular momentum transfer. The simulations are based on an implicit particle-in-cell finite element code [1] developed by the second author. The implementation of the model equations is benchmarked against an analytical solution for gravity driven flow in an infinite chute.",
