Numerical Examination of Sharp V-Notches Using Notch-Flank Displacement Collocation Method

Abstract

In this paper, a recently developed notch-flank displacement collocation technique (NDCT) is utilized to determine the notch stress intensity factors (NSIFs) of sharp V-notches. The mode I and mode II NSIFs are determined using the notch flanks opening and sliding finite element (FE) displacements, respectively. The rigid body displacements, which play an important role in the displacement components, are not neglected to calculate the NSIFs. The NSIFs of various benchmark configurations under pure mode I and mixed-mode (I/II) loading conditions have been calculated.
