Dislocation emission from crack tips
Philosophical Magazine A, 1991Abstract The emission of a dislocation from a crack tip is described in two dimensions by the build-up of a continuous distribution of infinitesimal dislocations ahead of the crack tip. The shape of the incipient dislocation is actually determined by the atomic potential in the glide plane but is approximated here by a truncated arctan (x/w) function ...

According to the elastic stress field solutions discussed in the previous chapter a stress singularity exists at the tip of an elastic crack. In practice, materials (especially metals) tend to exhibit a yield stress, above which they deform plastically.
