Abstract: Forming limit curves have been simulated using a Marciniak-Kuczynski type initial defect theory constructed for polycrystalline materials with a known texture. The technique has been generalized in the present work to account for the texture development during deformation. Three initial textures characteristic for aluminium sheets have been selected to study the effect of the initial textures as well as their development on the forming limits. It is demonstrated that both the initial textures and their subsequent development have important influences on the limit strains. The evolution of anisotropy decreases formability and also ''equalizes'' the forming limit curves. Experiments carried out in hydraulic bulging tests have confirmed the predictions.
