Yield Strength Determination in Pipe Hydrostatic Burst Test

The hydrostatic burst testing of steel pipe was carried out in accordance with AS2885.5:2002. It was shown that the yield strength of burst test could be obtained quantitatively based on the application of statistics and mathematical software by means of the analysis of the stress and added water volume curve. The software of Matlab was used for curve fitting and differential, and the yield strength of burst test was figured out quantitatively.
