Abstract
The contacts between cohesive, frictional particles with a few μm in size are studied. Discrete Element Model (DEM) simulations rely on realistic contact force models: A rather simple, objective contact model is used, involving the physical properties of elastic-plastic repulsion, dissipation, adhesion, friction as well as rolling- and torsion-resistance. Bulk properties like friction, cohesion and yieldsurfaces, can be modeled, but here, tensile strength tests after pressure-sintering are presented for different contact adhesion strength. The tensile strength increases with contact adhesion, but kinetic energy, coordination number and density decrease.
