| Abstract: | According to extrusion molding mechanism,proper simplification and assumption for flow behavior in extrusion die were made.And established mption for flow behavior in extrusion die were extablised mathematicla models of extrusion flow, and utilizing cross-fictitous-domain method to implement numerical simulation of 3-D profile extrusion die,Comparison fo results obtained by current method has been made wiht 3-D finiteelement solution or analytical solution.Results show a good accuracy of this proposed method. |
