A three dimensional (3D) thermo-elasto-viscoplastic constitutive model for FCC polycrystals

Elevated temperature has significant effect on the mechanical response of metals and alloys. Industrial processes often use high temperature forming to fabricate components of complex shape from alloys such as aluminum or magnesium that have low room temperature formability. Accurate forming models to integrate warm forming in computer aided engineering (CAE) in production environment has been hampered by a lack of constitutive relations at …
