不同加载路径下50W800G硅钢板的X射线应力分析

X-ray Stress Analysis of 50W800G Silicon Steel Sheet Under Different Loading Conditions

通过使用X射线并倾法,测量双轴拉伸过程中十字试样的应力应变关系。结果表明,双轴拉伸比单轴拉伸测试点的应变范围要大,从而可以指导生产中硅钢涂层的厚度。

The stress-strain relationship of the cross sample has tested by the X-ray and pouring method under the double-shaft-stretching process. The results show that the test point＇s strain range of double-shaft-stretching is bigger than uniaxial tensile, it can guide the production of the silicon steel about the coating thickness.
