摘要：
The contrasting analysis is carried out against approximate calculation, numerical simulation and the real measuring result of flow-in direction stress along the die-entrance in the rectangular drawing. It is considered that in the condition of non-uniform solution, part calculation has credibility to some extend. It is also pointed out that the shear stress along the flow-in direction existing near the junction of straight and curve edges is one of the major components of drawing pressure, and it is very important in the calculation of drawing load of non-rotational symmetrical drawing.
