Abstract
A device is developed for loading granular materials by shearing with air flow driven through the material without its pseudo-liquefaction. Internal stresses and dilatancy of a sample are measured depending on shearing angle. It is shown that shear modulus, characterizing material capability to resist shearing as air flow rate is increased, lowers while dilatancy grows.
