摘 要:A new modified conductivity model was established to predict the shear field stress of electrorheo-logical fluids (ERF). By using a cell equivalent method, the present model can deal with the face-center squarestructure of ERF. Combining the scheme of the classical conductivity model for the single-chain structure, a new formula for the prediction of the shear yeld stress of ERF was set up. The influences of the separation distance ofthe particles, the volume fraction of the particles and the applied elects"field on the shear yield stress were investigated.
