The effects of texture on formability of aluminum alloy sheets

The effects of typical texture components observed in rolled aluminum alloy sheets (i.e., copper, brass, S, cube and Goss texture components) on forming limit strains are numerically studied, utilizing the Marciniak–Kuczyński-type approach and a generalized Taylor-type polycrystal model. It is shown...

Description
Summary:The effects of typical texture components observed in rolled aluminum alloy sheets (i.e., copper, brass, S, cube and Goss texture components) on forming limit strains are numerically studied, utilizing the Marciniak–Kuczyński-type approach and a generalized Taylor-type polycrystal model. It is shown that only the cube texture component yields forming limits much higher than those for a random texture in a biaxial stretch range, while the other four texture components tend to yield lower forming limits. Furthermore, it is found that when the orthotropic axes of the cube texture material are inclined at 45° relative to the major stretch direction, abnormally high forming limits are obtained for near plane strain forming paths.
