Abstract

Abstract

The relocity and sirain-rate .field which are different from Avilzur's have been established in Caitesian coordinates. Using the integral as a function of the upper limitand integration depending on a parameler,an analylical upper-bound solution todrawing stress through idling rolls has been obtained in this paper.
- drawing through idling rolls,
- integral as a function of theupper limit,
- integration depending on a parameter,
- analytical solution
