“…The majority of engineering structures consist of steel welded components and are consistently subjected to alternating environmental loads. [1,2]，fatigue failure is a main failure mode in marine engineering. As is well known, localized stress concentrations result in severe notch stress gradients at weld toes, which leads to the initiation and propagation of fatigue cracks.…”

In this thesis, based on the theoretical derivation of notch mechanics, a simplified semi-analytical method has been established for the analysis of V-notch stress fields, thereby providing a theoretical foundation for rapid computation of notch stresses in welded joints. By comparing the notch stress results obtained through the semi-analytical method and those derived from finite element analysis (FEM), the accuracy of the semi-analytical method in analyzing notch stress fields has been verified. The findings indicate that the semi-analytical approach offers a distinct advantage in addressing notch stress analysis due to its mesh insensitivity.
