This analysis is carried out using the symmetric-Galerkin boundary element method, and a modified quarter-point crack tip element. As in case of non-contact fracture, it is shown that highly accurate SIFs can be obtained, even with the simple Displacement Correlation SIF technique. Moreover, with the modified crack tip element, the mesh on the crack does not need to be excessively refined in order to achieve high accuracy. This meshing advantage is especially important in the context of the nonlinear frictional contact problem, as the computing time for the iterative process strongly depends on the number of elements used. Several numerical examples are presented and the SIF results are compared with available analytical or reference solutions.308419 bytesapplication/pdfenCopyright: 2003 Springer-VerlagStress intensity factorsCrack frictionModified quarter-point elementsBoundary element methodsSymmetric-Galerkin approximationArticlePhan, A., Napier, J., Gray, L., & Kaplan, T.
