This paper is concerned with the post-processing formulation of the singularity subtraction technique in the dual boundary element method (DBEM) analysis of the mixed-mode deformation of general homogeneous cracked plates. For each deformation mode, the first term of the series of Williams eigenexpansion is used as a singular particular solution, valid in the neighborhood of each crack tip. At an internal point approaching each crack tip, the stress field is regularized locally with the… CONTINUE READING
