摘要
The force required to shear one-, two- and three-chain clusters of 230 mu m dia. glass beads in silicone oil was measured. In each case the shear force was proportional to the shear strain, the proportionality constant increasing with electric field and number n of chains in the cluster. The derived shear modulus G also increased with n. An extrapolation of the present results suggests that a cluster of 4-5 chains would give the stress enhancement factor of 10-20 observed for real ER fluids.
