Shear stress

  Isaac Newton was the first to express the basic law of rheology describing the flow behavior of an ideal fluid:

(21.1)

    where  is shear stress in fluid,  is apparent viscosity of fluid and  is shear rate. Apparent viscosity coefficient  needn’t be a constant as will be shown in this work.

For simple shear rate rules:
