Abstract

In this paper, determination of the accurate notch stress intensity
factors (NSIFs) have been demonstrated using a recently proposed technique:
The point substitution displacement technique (PSDT) for the sharp Vnotched
configurations. In this technique, certain optimal point(s) on the
notch flanks are obtained where the displacements are found to be highly
accurate. Using the PSDT, the NSIFs are determined from the finite element
(FE) displacements at these optimal point(s). The NSIFs of one pure mode I
and two mixed mode (I/II) examples have been determined and excellent
agreement of the present results with the published results is observed. The
PSDT is efficient, robust and easy to be implemented in the available FE
code.
