On the computation of the near-tip stress intensities for three-dimensional wedges via two-state M-integral

摘要

Singular stress fields around three-dimensional wedges are examined, and the near-tip intensity is calculated via the two-state M-integral with the aid of the domain integral representation. Two numerical examples demonstrate the effectiveness and accuracy of the present scheme for computing the stress intensities of singular stresses near the generic three-dimensional wedges.
