摘要
通过试验研究及对试验数据的回归分析,分别得到了里氏硬度计在C冲击装置和D冲击装置条件下既有钢结构建筑钢材里氏硬度——抗拉强度关系曲线,该方法为一种测试钢材抗拉强度的无损检测方法。
Experimental studies and regression analysis of experimental data show that when using HL hardness tester (under conditions of C-type/D-type impact device) to measure the tensile strength of steels from existing steel structures, the relation curves between Leed hardness and tensile strength of steel can be achieved. It may provide a non-destructive (NDT) method for testing tensile strength of steel.
