| Abstract: | Based on (he analysis of fragment flowing regularity in thedrawing process, a concept of flowing zone as well as consolidating zone has been presented. Ore flagment mechanical model and relevant formulas of drawing dynamics also has been established. According to variation principles the motion locus of flagment as well as the shape of flowing zone has been determined. A new developement in the drawing dynamics process has been realized thecretically. |
