The development of an UNDEX response validation methodology was discussed using numerical simulation and precision impact testing. An iterative process was used where an UNDEX response, preliminary UNDEX simulations, and impact simulations, led to the parameters necessary for a precision impact tests which generated an equivalent response. Correlation was found between the impact simulations and the precision impact test when the hybrid distributed impactor was explicitly modeled. This correlation between the precision impacts tests results and the simulated results validated LS-DYNA3D for that impact event and range of response.
