A Study of the Mechanics of Closed-die Forging. Forging Loads and Stresses in Closed-die Forging. Part Ii

摘要

The slab method of analysis for predicting forging stresses and loads has been applied to longitudinal (axial) flow, i.e., to extrusion-type forging. Both plane strain and axisymmetric deformations were considered. The flow models have been further studied, and the necessary equations for general use are derived. The flash-line location has been shown to have little effect upon maximum forging load if die-cooling effects are not too large. The present study represents a fundamental method for obtaining detailed information on the mechanics of closed-die forging. (Author)
