    Title: Study of U-shaped specimen concentration effect upon stress gradient
    Keywords: fatigue, fatigue life prediction, stress gradients, notch-tip stress distribution

    Abstract: The paper presents the results of numerical and experimental linear elastic analyses carried out to investigate the stress gradient of notched U-shaped specimens. Specimens with different U- shaped notch geometry subjected to uniaxial tensile loading have been considered. It was shown that the stress fields around the notch-tip are similar to each other regardless the notch shape. The most familiar analytical functions describing the stress field at the notch-tip have been presented. Some of the available approximation formulas are verified with the obtained numerical data. Comparison of results is shown and is discussed.
