三点弯曲试件塑性转动因子的试验研究

Effect of Yield Strength on the Plastic Rotational Factor of Three-point Bend Specimen

通过试验及理论分析，讨论了屈服强度对三点弯曲试件塑性转动因子的影响．试验结果表明：随着屈服强度的增加，塑性转动因子增大．

The effect of yield strength on the plastic rotational factor of three - point bend speci-men is discussed through experiments and theoretical analysis. The results show that the plasticrotational factor increases with the increasing of yield strength.
