【摘要】 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。更多还原

【Abstract】 The Corresponding diagram on stress-strain state not only describes the relation-ship betueen stress and strain state at any one point imaginally,but also corresponds eachpoint in real deformed zone to state-diagram,which reflects deformed proless.Therefore,this diagram can be used to analyze all kinds of patterns during metal plastics forming.更多还原
