    Influences of non-uniformly distributed forming loads on deformation sequence and texture evolution in tailor heat treated Al6014 blanks by Nan Xiang, Meng-han Yang, Wan-ting Sun, Tao Huang, Hai-rui Zhang, Peng-yi Wang, Fei-yang Cheng

    Published 2025-01-01
    “…Nevertheless, the challenges are also introduced, such as excessive plastic deformation and increased risk of rupture in the softened region, leading to diminished formability of the sheet metal. In this study, to address these issues, a control strategy that utilizes non-uniformly distributed pressure (NUDP) to regulate the regional deformation behaviors of tailor heat treated blank (THTB) is proposed. …”
