Abstract
The shear stress-strain relationships of the electrorheological fluid were set up by taking into account the influence of both the microstructure of the fluid and the exact interaction between two particles in an electrorheological fluid calculated by using the modified dipole model and the conductivity model respectively. On this basis, and by considering the fracture and reconfiguration process in the post-yield state of this material, its dynamic yield stress was obtained. The calculation result indicates that (1) the dynamic yield stress is lower than static yield stress by about 25%; (2) the dynamic yield stress of the electrorheological fluid increases nearly linearly with the increase of volume fraction at the small volume fraction and gets their maximums at rather large volume fractions of about 0.4-0.5.
