Under macrostrain large strain , the equivalent effective stress of pure torsion was higher
在大应变下，由扭转实验测得的等效应力值较高。
The equivalent effective stress - strain curve of pure torsion was five - six times longer than that of tension experiment
由纯扭转实验得到的等效应力应变曲线较拉伸实验延长5 - 6倍。
When we draw the stress - strain relation of monotonic tension and pure torsion at the same co - ordinate namely equivalent effective stress and equivalent effective strain co - ordinate , it is obviously that the equivalent effective stress - strain curve of monotonic tension and pure torsion are basicly superposition while the equivalent effective strain is smaller . but equivalent effective stress level of monotonic tension was higher a little than that of pure torsion
把a3钢试件单一拉伸和纯扭转时应力应变关系绘于同一个坐标中即等效应力和等效应变坐标中，可以看出当等效应变较小时拉伸实验得到的等效应力应变曲线与纯扭转实验得到的等效应力应变曲线基本重合。但单一拉伸较纯扭转得到的等效应力要略高一些。
