ABSTRACT:
A computer controlled shear cell (CCSC) tester for bulk solids, especially powders, that allows the determination of a Yield Locus curve from a single test procedure. The principle of the CCSC is that yield states can be maintained in a test cell over a range of normal and shear stresses in the same test. This leads directly to a Yield Locus curve. With its flexible design, the CCSC can also be used as a Jenike shear cell or a direct shear cell. Use of the CCSC allows the testing time and amount of material needed for testing to be reduced as compared to current testing methods.
