Abstract
The usual methods are not suitable for the calculation of prestressed forging dies. The reasons are the complicated shape of the die impression as well as the dynamic and thermic conditions. New guidelines for design of prestressed forging dies and solutions for reducing stress concentrations were found in examination of three problematic cases of production dies.
