  Using molecular dynamics simulations, we study the steady shear flow of dense
assemblies of anisotropic spherocylindrical particles of varying aspect ratios.
Comparing frictionless and frictional particles we discuss the specific role of
frictional inter-particle forces for the rheological properties of the system.
In the frictional system we evidence a shear-thickening regime, similar to that
for spherical particles. Furthermore, friction suppresses alignment of the
spherocylinders along the flow direction. Finally, the jamming density in
frictional systems is rather insensitive to variations in aspect-ratio, quite
contrary to what is known from frictionless systems.
