摘要
The present paper describes a systematic investigation of possible flow imperfections in forging of an H-shaped profile. The influence of geometry and volume of the slug and of friction in the tool/workpiece interface on flow are investigated by numerical as well as physical modelling. A comparison between two different FE- codes, DEFORM ans Forge2 and physical modelling applying parafin wax shows good agreement between the different methods of analysis. Based on the results a formability diagram has been established for forging of H-shaped profiles.
