| Abstract: | This paper gives a new method, the semi-analytic method, which is more convenient than the three-dimensional finite element method. It is demonstrated that the problem which calculates the three-dimensional non-newtonian melt's flowing in the extrusion nose of plastic sheet is greatly simplified. |
