Are there any numerical or analytic formula for the estimation of dislocation density?

1. There are several experimental microscopy techniques for the calculation of dislocation density; but are there any reliable numerical ones, as well ? like those, which least include experimental parameters, except for some initial ones, like the initial density of dislocation, such as Reid's formula [1].

2. as a result of dislocation accumulation after deformation, slip bands form. are there any numerical techniques for slip band density estimation?
