Abstract
The effect of elastic strains in the steady‐state visco‐elastic fluid flow under the rolling process is analysed quantitatively. Spurious oscillations in the stress deviator and pressure fields are precluded and the rate of convergence is improved when the Petrov–Galerkin method, which is based on a least‐square method, is introduced into the finite element equation for the constitutive law.Keywords
