A Direct Shear Test for Powders and Granular Materials
Journal of the Research Association of Powder Technology, Japan, 1974 A new method for direct shear tests was devised to measure easily the flow properties of a powder and a granular material. This method is based on the stress resulted from expansion in volume of the specimen during a shear test.Expansion is caused by the movements of each particle in shearing zone.
