Query: Shear Is Not Always Simple: Rate-Dependent Effects of Flow Type on
  Granular Rheology   Despite there being an infinite variety of types of flow, most rheological
studies focus on a single type such as simple shear. Using discrete element
simulations, we explore bulk granular systems in a wide range of flow types at
large strains and characterize invariants of the stress tensor for different
inertial numbers and interparticle friction coefficients. We identify a strong
dependence on the type of flow which grows with increasing inertial number or
friction. Standard models of yielding, repurposed to describe the dependence of
the stress on flow type in steady-state flow and at finite rates, are compared
with data.
