DOI: 10.1016/j.ijsolstr.2019.08.004
Abstract: Abstract Sheet metals usually exhibit varying degrees of anisotropy due to formation of texture during rolling process. The grain structures and distributions in sheet normal direction may also be different from that within the sheet… read more here.

DOI: 10.1016/j.jmatprotec.2017.10.004
Abstract: Abstract Under certain strain paths (e.g., balanced biaxial) and during some forming processes (e.g., incremental forming, micro forming), sheet metals may deform and fail without forming a local neck. In these cases, it is challenging… read more here.
