The objective of this Phase I study was to establish quantitative relations between process variables in radial forging of gun barrels. Thus, a basis would be established for optimizing the process conditions. The slab method of analysis has been used to predict the stresses, and the loads in radial forging of rods and tubes. In addition, the upper-bound method has been applied for predicting the metal flow, the total forming energy, and the loads in radial forging of rods and tubes. Both the slab and the upper-bound applications have been computerized by taking into account the effects of strain, strain rate, and temperature upon the flow stress of the material being forged. Forging loads have been predicted for selected forging conditions and a parametric study has been used to determine the relations between friction, die angle, and forging load.
