Finally, the effect of hydrogen on a dislocation source at a crack tip is investigated.

For the numerical study, image forces on a dislocation in two- and three-layer systems are calculated.

To evaluate predictive capabilities of the two theories, we perform atomistic computer simulations of Al segregation on a dislocation in Ni.

The image forces exerted on a dislocation due to the interfaces are also calculated by means of the generalized Peach Koehler formula.

Second, the problem is modeled using a crystal plasticity finite element method which is based on a dislocation density-based constitutive model.

The observed grain boundary sliding and migration can be explained based on a dislocation mechanism for sliding which is based on the movement of lattice dislocations along the grain boundary by a combination of climb and glide.

A simple model for the strength in this regime of grain sizes is developed from classical dislocation theory, based on the bow-out of a dislocation from a grain boundary dislocation source.

They support the successive steps of the corrosion enhanced plasticity model, which is based on a local softening in the SCC crack region and on the repeated formation of a dislocation pile-up at some distance ahead of the crack.

The same constitutive law is used at the grain level, relying on a dislocation-density-based description of work hardening and accounting for the latent hardening due to the presence of twins.
