The plastic deformation of a highly concentrated electrorheological suspension of a polarized particles in a dielectric liquid medium in a strong electrical field near the breakdown of its structure takes place with a deformation rate that is far less than the rate of relaxation of the lattice of chains of bound particles by successive local microflows (jumps). Impulse is transferred in each microflow, and then the structure of the suspension recovers to a new microfusion at the point of concentration of the “elastic” energy. The transferred momentum and the corresponding resistance force are proportional to the square root of energy, and in the polarization saturation case to the square root of the intensity of this field, which agrees with the experimental data [1].
