Abstract
This paper addresses some of the issues involved in predicting fracture toughness of structural metals by linking the fracture process occurring at the crack tip through the plastic zone to the outer elastic field of a macroscopic crack. The link is extremely nonlinear giving rise to a macroscopic toughness which can be magnified many times the intrinsic work of the fracture process. The two principal fracture mechanisms considered are cleavage and void nucleation, growth and coalescence.
