The basic theoretical methods such as Slab method, UBET, SlipLinemethod, FEM, and FVM have been used in the research of metal plastic forming technology.
研究金属塑性成形规律的理论方法现在有主应力法、上限法、滑移线法、有限元法和有限体积法。

The deforming force of cone-die direct extrusion is solved by a mathematic method based on the simplified flow model ofslipline field.
The theory ofslip-line field is an effective method for problems of plane strain of perfect plastic solids, and the circle-fan field is used frequently.
