Abstract
Dissociation of dislocations into partials, which are not freely mobil e on the plane of dissociation, is discussed in the framework of a mod el where the frictional force can be described by a Peierls potential. It has been shown that, when the metastable positions of dissociated dislocations are not considered, the resulting energy of the stacking fault connecting two partials may be underestimated.
