Communication avec acte;AYED, Yessine; MAREAU, Charles; GERMAIN, Guénaël (AIP Conference Proceedings, 2018)
For metallic materials, fabrication processes (e.g. machining and forging) may involve important strain rates and high temperatures. For such severe loading conditions, the development of damage is often associated with ...
