Abstract:
It has been
proved by physical simulation that there exist radial and
tangential tension stresses in the central zone (except the
rigid zone) of the deformed body when a circular cylinder in
upsetting between common flat platens. The method of physical
simulation is new, simple, reliable and practical.
Key words:
