Abstract
Continuous dislocation theory has not had great practical applicability, owing largely to the dislocation density tensor being an average quantity that includes very limited information about dislocation structures and energetics at length scales smaller than the averaging volume. Here we present a straightforward way to include the effects of underlying structure based on moments of the dislocation distribution and show that the addition of a small number of order parameters enables one to accurately characterize the energetics.
