It was recalled that continuous dislocation theory had not enjoyed great practical applicability; due largely to the dislocation density tensor being an average quantity that included very limited information about dislocation structures and energetics at length-

scales smaller than the averaging volume. Here, a straightforward method was presented for including the effects of underlying structure. It was based upon moments of the dislocation distribution and showed that the addition of a small number of order parameters permitted the accurate characterization of the energetics.
