Abstract
This paper proposes a method for the evaluation of the Stress Intensity Factors (SIFs) of embedded cracks lying along the bisector of the welded toe angle. The SIFs are calculated on the basis of the JV parameter (the extension of the J-integral to sharp V-notch) for a path radius equals to the crack extension without modeling the crack. Numerical calculations performed in the paper show the stability of the proposed method also with course meshesFile in questo prodotto:
