摘要
就目前冷轧扭钢筋拉伸试验结果有效率较低的问题,对其试验方法从试样选择、夹具及夹持方式、加荷速度以及标距标点和测定性能数值的改进等方面加以探讨。
This paper deals with the problem of low efficiency in the experiment of tensile testing cold rolled and twisted bars and puts forward some suggestions to improve the experiment in test pieces choosing,clamping apparatus selecting,charge speeding,gage length marking and data measuring etc,so as to get better experiment efficiency.
