For successful implementation of EAF in manufacturing industries, one area that needs to be addressed is the predictability or material response at a bulk level. This chapter introduces the modeling strategy for the electroplastic effect at the macroscale, which are used for compressive modeling (Chap. 5 ) and tensile modeling (Chap. 6 ). For macro-level modeling of EAF in Chaps. 5 and 6, the models use a coupled thermo-mechanical approach based on energy and displacement continuity. Additional laws utilized in Chaps. 5 and 6 include: the first law of thermodynamics, Joule’s first law for heat generation, Fourier’s law for conduction, and Newton’s law of cooling.
