EVALUATION OF UNCERTAINTY IN MEASUREMENT ON TENSILE STRENGTH OF IRREGULAR-SHAPED TUBES WITH INTERNAL TEETH
The evaluation of uncertainty on tensile strength test for section steel tube with internal tooth was made by weighting method. The results reveal that,Rm=400.5 N/mm2 (MPa),U95=5.6 N/mm2 and νeff=32,respectively. It is considered that the method will provid reference for uncertainty evaluation of tensile strength test of similar products.
