2. There are various methods of writing the stresses in the space-fixed coordinate system, which are based on a constitutive equation derived for a moving material element. Here, use is made of the method based on the Oldroyd transformation. For greater details see Malkin, A. Ya., Rheol. Acta, 7, 335 (1968).
