Abstract
A model governing a steady flow of a
viscoplastic material between coaxial
cylinders is proposed. Nonlinear
velocity sensitivity typical of
superplastic materials is taken into
account. An algorithm of calculating the
characteristics of the material is
developed. The algorithm is based on the
experimental data on moments and angular
velocities of the rotating coaxial
cylinders. The stability of the
algorithm to errors in the initial data
is estimated.
