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.
