The effect of contact torques on porosity of cohesive powders
Guido Bartels, Tamas Unger, Dirk Kadau +2
The porosity of uniaxially compacted cohesive powders depends on the applied stress (including gravity). The case, where these stresses are weak, is considered. The compaction resu…

Macroscopic and Microscopic Investigation on the History Dependence of the Mechanical Behaviour of Powders
D. Kadau, L. Brendel, G. Bartels +3
As an example for history dependent mechanical behaviour of cohesive powders experiments and computer simulations of uniaxial consolidation are compared. Some samples were precompa…

Frictional coupling between sliding and spinning motion
Zeno Farkas, Guido Bartels, Tamas Unger +1
We show that the friction force and torque, acting at a dry contact of two objects moving and rotating relative to each other, are inherently coupled. As a simple test system, a sl…
