| Description: | The goals of Test Case 1.1 are examples to assess the reliability and consistency of LS-DYNA® in lagrangian impact simulations on shells. This is achieved by testing various material models, element formulations, contact algorithms, etc. As a reference, ballistic data for this problem were provided by NASA Glenn Research Center. Tested are cases for a 7"x7"x0.04" 304L SS steel plate. For each of the 12 cases, two simulations are performed to verify that the ballistic limit from the simulations is consistent with the experimental result. One simulation at 95% and one at 105% of the experimental ballistic velocity. Also NASA Glenn Research Center provided input data for various materials and material models. In order to ensure cross-platform consistency, these cases are run on several platforms supported by LS-DYNA®. |
