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?

Despite the controversial debates concerning a unified theory, the continuum plasticity has evolved during the last few decades and an uncountable number of articles has been published on the subject. The proposal of Lee to decompose the deformation gradient, F, into elastic part F^e and plastic part F^p (i.e. F=F^eF^p) combined with the principle of maximum plastic dissipation is used in many publications to formulate the ensuing developments.
