WebFlowability is often described on the basis of the flow function (Figure 1) [1] derived from shear testing. The flow function is a graph relating a major principal stress (σ 1 ) to the … WebWith Formula (23), the flowability of a powder could be calculated from the values of the consolidation stress σ 1 and the compressive strength σ c (unconfined yield strength) of the material. The larger the value, the easier it was to bring the powder from the quiescent state to the flow state for a given value of compressive stress.
