Analysis of Metal Deformed Flow under Adhesive Friction by Ring Upsetting

It is a complex coupling of multi-physics field for metal deformed flow behavior under the condition of adhesive friction, which has been studied in this paper. In this paper, ring upsetting has been carried out with various press amounts. By comparisons of the transient displacement figure of internal & external metal particles under different press quantities, deformed flow state of metal particles is obtained, and inverse flow is found under the adhesive friction. Based on transient displacement obtained by ring upsetting, the flow orientation of the whole specimen is specifically acquired by means of piecewise cubic hermite polynomial interpolation. In the end, representation model of deformed flow behavior is put forward to illustrating and predicting the flow behavior of metal particles.
