| Abstract: |
| This paper analyzes the influence law of samples, measuring tools, testing machine, extensometers and test operation on yield intensity, which aims at the accuracy of yield intensity of arc-shaped pipe. Deviation of these factors on the experimental results are analyzed and summarized to provide reference data for the assessment of the results of such trials. |
| Key words: pipe arc-shaped samples yield strength |
