Abstract A method for determining the response of a munition to Fragment Impact (FI) stimulus based on hydrocode modeling and statistical analysis is presented. modified version Hugh James Criterion coupled logistic regression technique obtain normalized distance from initiation threshold as determined experimentally through FI tests. The has been shown correlate well with observations at multiple impact velocities various configurations mitigation schemes. total 65 shots have completed date TOW 2B warhead two different shotlines, data will be presented here. shotlines are cylindrical section boattail warhead. When fit overall set, 51 out correctly categorized.
