Specifications For BM2: Underbody Cross Member Panel.

The article reports on a study to benchmark springback prediction capability of various software and skills of users on an underbody part mostly dominated by bending effect. The simulation process of stamping a cross member panel consists of three operations: forming, trimming and springback. In this benchmark, participants are allowed to use either physical beads or line beads in forming simulation. The information of physical bead geometry and bead centerlines is provided in the Nastran mesh file and IGES file.
