Abstract

In order to estimate flowability of a cohesive powder, an expression was proposed for a ratio of strength to unit weight as a function of compression stress of powder. The expression was verified with experimental data of various strengths measured by tensile test, shear test, compression test and other tests as shown in many previous papers.<br>In the special case of that the strength identified with the compression stress, an equation was obtained between the compression stress and the packing fraction of the powder. The strength therefore was shown by a power function of the packing fraction alone with a favorable comparison between experimental previous data. A conclusion was shown that the strengths, the compression stress and the packing fraction were mutually related.
