The influence of the crystallographic texture on the biaxial stretchability of AA 5182 sheet

Crystallographic texture plays an important role in mechanical anisotropy. For a sheet material in biaxial stretching, texture has a significant effect on the formation of strain localization. In this work, the effects of different textures on the biaxial stretchability of AA 5182 sheet materials were studied. The results indicate that for textured AA 5182 sheet materials, the biaxial stretchabilities were closely associated with the crystallographic texture. It was found that the Olsen cup values were closely correlated to the calculated strain path values and limit strains. For a sheet material with a proper texture combination, the biaxial stretchability is greatly improved.
