The goal of this project is
to compute the stress required to nucleate a crack at
the interface between two materials. Atomistic
simulations are used to compute atomic-scale
traction-displacement relations for the interface.
The traction-displacement relation is used in a
discrete dislocation computation that predicts the
critical remote stress required to separate the
interface. J. Gullickson, A. Needleman, P.
