Abstract
The intergranular cohesion of granular masses is investigated with an apparatus which in principle is a Couette viscometer. Rheologically, the granular mass behaves as a plastic solid, with the difference that the plastic yield point S0 of a granular mass is a function of the pressure p which acts normally on the yielding plane. In an (S0, p) diagram, a cohesionless mass will be represented by a straight line passing through the origin and having a limiting slope of 0.193, while a granular mass with cohesion will show a lesser slope, the departure from the limiting value being a convenient measure of the cohesion. Powders which are not free-flowing will be represented in the (S0, p) diagram by lines, which are not necessarily straight, with an intercept on the S0 axis.
