Ductile rupture of prestrained X100 pipeline steel sheets
Abstract : The mechanical and damage behavior of a X100 steel after prestrain is studied in thiswork. Experimental results show both a plastic and rupture anisotropy: the T direction exhibits ahigher ultimate stress but the lowest ductility and toughness. Prestrain reduces ductility and crackgrowth resistance. A model able to represent the plastic and damage behaviour of the material beforeand after prestrain is proposed. The model incorporates plastic anisotropy, kinematic hardening, voidgrowth of the primary cavities, nucleation of secondary voids on carbides. Using the model afterimplementation in a FE software, allows to reproduce experimental trends.
