The increasing importance of powdered materials fabrication has led to an increasing emphasis on the understanding of the powder behavior during compaction. During compaction, a powder mass undergoes densification owing to various mechanisms, i.e. sliding, rotation, deformation and/or fracturing of the constituent particles. These densification mechanisms are very dependent upon the powder char...
The subloading-friction model is capable of describing static friction, the smooth transition from static to kinetic friction and the recovery to static friction after sliding stops or sliding velocity decreases. This causes a negative rate sensitivity (i.e. a decrease in friction resistance with increasing sliding velocity). A generalized subloading-friction model is formulated in this article...
