An Upper-Bound Solution for Elevated Temperature Wire Drawing

Although the elevated-temperature drawing of wire has been employed in industry for a number of years, the process has not been investigated systematically and many facets of the process are not yet understood. Generally, exploration of the mechanics of wire drawing has been confined to cold working, for which the effects of strain-rate and temperature on the flow stress can be neglected: it is believed that no attention has been paid to the mechanics of wire drawing at elevated temperatures.
