... 10 07 2009 A major issue of applying the crack-tip opening angle (CTOA) approach to fast ductile fracture control is to characterize material toughness (CTOA c ) using laboratory-scale specimens and to recommend a mill test. In this report, existing direct and indirect CTOA measurement...

.... The review covers (1) constraint theories and experimental evidences, (2) constraint models for brittle and ductile fracture, and (3) limitations of current constraint models. The paper closes with thoughts on the applications of the constraint models and theories to ductile fracture processes, which...
