A combined phenomenological model for the representation of anisotropic hardening behavior in high strength steel line pipes

, 2010
International audienceLine pipes have anisotropic mechanical properties, such as tensile strength, ductility and toughness. These properties depend on both prestrain during the cold forming process and on the anisotropy of the mother plates.
