Materials Science of Fracture Processesare able to provide high stress-concentrations. The cracks may be present . as a consequence of manufacturing processes; they may be nucleated by plastic deformation; or they may be introduced deliberately, e.g. by fatigue, to provide standard precracks in testpieces.

Raghu N. Kackar,Anne C. Shoemakerlement may actually involve an enhancement of crack tip plasticity, as has been suggested by the work of Lynch (2) and Birnbaum and co-workers (3). In this paper, we will discuss how the calculations are done and what we conclude from them.

Mechanics of Brittle Cracking of Crystal Lattices and Interfacesgy of grain boundary embrittlement by P and Sn in Fe, and of “cohesion enhancement” by C, can be at least partly understood as an effect of the various segregants on altering the work necessary to separate an interface against atomic cohesive forces.

A. Le Yaouanc,L. Oliver,O. Pène,J. C. Raynaltrain to cause ductile failure by void coalescense does not depend on the state of strain. The void growth calculations and the experiments are reconciled by the view that ductile failure initiates in the most favourable statistical irihomogeneity in which the local strain state does not necessarily correspond to that applied remotely.
