Abstract
From the Introduction: For cracked bodies exhibiting a limited amount of plasticity, linear-elastic fracture mechanics adequately describes the singular stress field existing near the crack tip. The fracture toughness parameter, Kic, characterizing this singularities magnitude for crack extension, has had sufficient investigation to provide an extremely useful tool for judging a material's susceptibility towards onset of crack extension from flaws. Unfortunately, not all engineering structures can be analyzed with this linear elastic approach due to the high toughness of the material being used or the large crack tip plastic zone relative to the dimensional characteristics of the structure at fracture. In such situations, an analysis must be made describing the singularity within the plastic zone at the crack tip.
