When we take a stroll on the beach, we walk on the sand without any trouble. The sand appears solid and is difficult to compress. When we put the same sand grains in an hourglass, they behave very ...

Shear transmission in granular flow is intrinsic to systems ranging from geophysical flows to industrial processing, and peculiarities in granular shear response have consequences that can be dramatic ...

Dense flows of grains driven by gravity down inclines occur in nature and in industrial processes. Natural examples include rock avalanches and dune slides. Applications are found in the chemical, ...
