摘要：
The paper deals with the influence of micro structural material aspects on the localized necking in sheet metal forming. The approach developed accounts for various micro structural material aspects as crystallographic slip, work hardening at micro structural level and lattice rotation which induces the texture evolution. The analyses are performed using the linear stability analysis combined with a polycrystalline model to build Forming Limit Diagrams and to study their evolution with the initial and induced anisotropy. © 1998 Elsevier Science B.V.
