Recent results have shown that different methods to obtain line integrals for the energies of dislocation loops, and, by extension, of arbitrary dislocation configurations, give different results when a constant core cutoff parameter is used. We show that a self‐consistent choice of different cutoff parameters for the different methods removes the disparity in energy. The choice of cutoff parameter is discussed in the context of core–core interactions, important in the correlation of elastic estimates of energies with atomistic results.
