Atomistic modeling of fracture

Atomistic modeling of fracture is intended to illuminate the complex response of atoms in the very high stressed region just ahead of a sharp crack. Accurate modeling of the atomic scale fracture is crucial for describing the intrinsic nature of a material ...

The mechanics of crack-tip dislocation emission and twinning

Predrag Andric

Dislocation emission from a crack tip is a necessary mechanism for crack tip blunting and toughening. A material is intrinsically ductile under Mode I loading when the critical stress intensity

K_{Ie}

for dislocation emission is lower than the critical s ...
