应力－应变状态对应图

The Corresponding Diagram on Stress-strain State

本文介绍的应力－应变状态对应图是对有关这方面［１］、［２］论述与推导的进一步改进与补充，应力－应变状态对应图不仅可以形象地描绘一点的应力状态和应力应变之间的对应关系，还可以将实际变形区中的点对应到状态图上，反映出加工变形过程中应力应变的变化规律。因此可以利用该图来帮助分析各种金属塑性加工的成形规律。

This corresponding diagram on stress-strain state is an furthur modification andsupplement to references[1],[2] in this paper.The diagram not only describes the relation-ship of stress and strain state at any pont vividly,but also correspoinds each point in real de-formed zone to state-diagram,which reflects the changing rules of stress-strain in deformingprocess. Therefore,this diagram can be used to analyze all kinds of patterns dtiring metalplastic forming.
