The U.S. Army Research Laboratory s SurvivabilityLethality Analysis Directorate ARLSLAD is developing a modeling proficiency for ground vehicle systems exposed to under-body blast UBB threats with predictive crew casualty analysis capabilities to support live-fire test and evaluation LFTE. This report details a comprehensive comparison of two software suites used for modeling anthropomorphic test devices ATDs in blast environments conducted to down-select to one for future modeling efforts. After extensive use of both software suites to model laboratory and live-fire experiments with ATDs, it is clear that the mathematical dynamics model MADYMO software suite offers many advantages over articulated total body ATB. These advantages include reduced model setup time and pre-processing, increased amount of model features, increased level of temporal and special resolution, a larger user community, and thorough commercial software support. From these results, the logical path forward for the under-body blast methodology UBM program is to use the MADYMO software suite for modeling ATD response to blast loading.
