Abstract: 

The paper presents problem of transition from one steady-state conditions of viscoplastic fluid flow to another between parallel planes. The problem definition is given within the limits of five-parameter model, which permits to take up differences between behavior under stress and without stress and possible slippage along the solid walls. Hysteresis of deformation is considered by means of model of smooth transition from adhesion to slippage. The solution is determined by method of momentary eigenfunctions of Melamed-Grinberg.
