Abstract: Reynolds equations of Ostwald non-Newtonian fluid in various
zone of drawing process are derived. That the distribution
figures of oil film thickness, pressure and inside stress are
obtained by Ostwald non-Newtonian model and large strain elastic
plastic finite element is analyzed by drawing examples.
Key words: Drawing
Hydrodynamic lubrication Non-Newtonian fluid
