Abstract

PDF

Literature review on mathematical and FE modelling of developed strain distribution during ECAE process is reviewed and analyzed. From the last few decades, a variety of models have been developed and discussed at different aspects of ECAP. In hypothesis, the developed strain during ECAP depends on the geometry of the ECAP die, which is die channel angle (ϕ) and corner angle (ψ). This short review critically reviews the mathematical models of ECAE process and impact of ECAP die angles on deformation homogeneity through finite element methods
