Fig. 6

In all panels curves pertaining to tension are shown in orange and curves pertaining to compression are shown in blue. a Ratio of the imposed straining rate to the total dislocation flux \(\dot {\varepsilon }/\dot {\gamma }\) (solid lines) and ratio of the rate of plastic strain accumulation to the imposed straining rate \(\dot {\varepsilon }/\dot {\varepsilon }_{zz}^{p}\) (dashed lines). b Ratio of the flux due to screw dislocations to the flux due to non-screw dislocations. (c) Densities of screw (solid lines) and non-screw (dashed lines) dislocations as functions of strain
