New theory for. Mode I crack-tip dislocation emission

William Curtin, Predrag Andric

A material is intrinsically ductile under Mode I loading when the critical stress intensity K-Ie for dislocation emission is lower than the critical stress intensity K-Ic for cleavage. K-Ie is usually evaluated using the approximate Rice theory, which pred ...

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 ...

Atomistic modeling of fracture

William Curtin, Predrag Andric

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 ...

Failure of mounting bolt of helicopter main gearbox support strut

Predrag Andric

The mounting bolt of helicopter main gearbox support strut was fractured into two pieces during the flight mission. The fracture occurred at the root of the first engaged thread of the bolt-nut assembly. Visual inspection of the fracture zone revealed crac ...
