| Description: | This test case, provided by Boeing, is a ballistic impact of a steel projectile on a composite BMS8-212 target, which is an outdated Boeing military material in a 16-ply laminated composite lay-up. Solid elements ELFORM=1 and MAT_162 (*MAT_COMPOSITE_DMG_MSC) are used to model the composite. MAT_162 requires a separate license from Material Science Corporation. Delamination is modeled by the use of contact *CONTACT_AUTOMATIC_SURFACE_TO_SURFACE_TIEBREAK, OPTION=7 (DYCOSS Discrete Crack Model). Measurements were done at UC Berkeley - Mechanical Engineering Department. The measured impact speed is 4758 in/sec. The measured exit speed is 4133 in/sec.
