Abstract:

The Warrior Injury Assessment Manikin WIAMan Engineering Office has been developing a biofidelic anthropomorphic test device ATD to enable the live-fire test and evaluation community to address the deficiencies associated with the use of the Hybrid III ATD to assess the risk of mounted-Soldier injuries subjected to under-body blast. A finite-element FE virtual modeling tool has been developed to support the design and development of the WIAMan ATD. Material characterization is one of the critical challenges facing the ATD modeling community because of the lack of adequate material models and inconsistency between material models available in different FE codes. The WIAMan modeling and simulation team systematically characterized the material properties using experimental data for 8 polymeric materials used in key components in the WIAMan ATD Tech Demonstrator. Two modeling teams independently simulated the WIAMan ATD in vertical accelerative loading simulations using 2 different modeling platforms LS-DYNA and Velodyne. The approaches to derive the material parameters, constitutive material models, and the fitting algorithms are discussed in this report. A brief summary of the whole-body simulation results of an ATD response due to vertical accelerative loading is provided and compared to illustrate the predictive capability of the derived material models.
