Application of Weibull distribution to describe SN curve with using small number specimens
P Strzelecki, T Tomaszewski - AIP conference proceedings, 2016 - pubs.aip.org
The paper presents a standard approach to the determination of the SN curve. It also
presents an alternative approach requiring fewer samples. The proposed method was
verified based on test results for steel S3555J2+ C. The tests were performed by rotating
bending. Based on the resulting curves, it was determined that a sufficiently accurate SN
curve could be obtained using 9 samples, which is fewer than the standard 14 samples. In
addition, a different scatter band depending on sample loading level within its limited …
