4.5.2.1 Conclusion for Constant Current Density Empirical Modeling
Using prior empirical models, the NCCD data were fitted to expand the current
capability of the original empirical model. Also, as a result of the CCD tests, a
newly developed flow stress predictor was introduced to predict the flow stress
for CCD tests as the prior empirically based model was not capable of being
employed. The results of the CCD predictor showed excellent mapping capability
of both the 304 Stainless Steel and Ti-6Al-4V materials.
4.6 Macroscale Modeling of the Electroplastic
Effect Conclusions
This chapter provided an introduction to the modeling approach taken in Chaps.

. In particular, the concept of the EEC was presented. The EEC is defined as
the amount of electrically that contributes directly toward plastic deformation ver-
sus the total amount applied to the process. To establish the EEC, two methods were
presented that included a mechanical-based and thermal-based approach. After estab-
lishing the procedure with examples, the two approaches were compared and they
provided the same approximation for the EEC. Last, this chapter included a method-
ology and examples of empirical modeling for the bulk flow stress during EAF. The
empirical models were constructed for both NCCD and CCD experimental data.
