Borouchaki, TroyesThis work aims to develop a fully coupled numerical methodology required for virtual sheet or bulk metal forming. Based on the “strong” thermo-elasto-visco-plastic-damage coupling, this procedure allows the ductile damage prediction during the forming of any metallic components. This gives an efficient “virtual” way to “optimize” any forming or machining processes with respect to damage occurrence. Accordingly, we are able to avoid the damage occurrence as in deep drawing, forging and so on ... or to enhance the ductile damage initiation and growth in o...
