Simulation of metal flow during upsetting of flat profiled billets
摘要
The article analyses the results of virtual experiments and studies of existing kinematic schemes of metal flow, in particular, normal and radial schemes. Based on the “equi-theory”, the EQUI software package, which can serve as an effective tool for simulating the pattern of metal flow along the billet during metal pressure treatment, has been developed. The software allows performing express analysis and prediction of shape changes in flat billets and simulating spatial diagrams of contact stresses.
