Abstract
The phenomena of shear stress relaxation in liquids was investigated. The system size necessary for observation of this effect increases with the decrease in temperature. It was observed that the liquid can store deformation energy and sustain shear stress only for a time shorter than its shear stress relaxation time. The cooperative effects in stress relaxation causing an increase of relaxation time and viscosity do not require the existence of domains of different order. It was found that the system size needed for complete stress relaxation under strain decreases with increase in temperature.
