Abstract:A series of experiments performed in a novel shear cell clearly demonstrate that the presence of a combined load alters the mechanical response for an aggregated suspension. Imposing a shear field on the particle network reduces the compressive strength of the network. The magnitude of this reduction in compressive strength is controlled by the relationship of the applied shear rate to a critical shear rate, g&d2;, which is a material property of the suspension. Similarly the presence of an applied normal load increases the measured dynamic yield stress. However, the magnitude of this increase is very small, suggesting that Coulombic friction plays a very minor role in the mechanical response of such aggregated systems. This study has wide-ranging implications for the design and control of solids handling processes which are ubiquitous in modern chemical and ceramics industries.
