successive elimination

Then taking the influ- ence of metal forming temperature and velocity on flow stress into account, the formulation of contact stress in the groove of extrusion wheel is deduced by means of the successive element method, which provide theoretical basis for the continuous extrusion equipment.

在变形区划分的基础上，提出了合理的基本假设，采用逐次单元法推导出连续挤压轮槽中接触应力的计算公式，为连续挤压设备的设计提供了理论依据。
