Abstract:

The Warrior Injury Assessment Manikin was developed to provide an instrumented anthropomorphic test device ATD specifically designed for underbody accelerative loading test environments. This first of its kind ATD was designed to exhibit human-like kinematic responses to underbody blasts. To achieve that goal, the ATD used numerous polymeric materials for component parts that simulate human tissue and enable compliance in the ATD. The polymeric materials mechanical properties range from soft and flexible low-durometer polyurethanes to rigid high-modulus plastics. All materials are commercially available. This report presents tensile and compression properties for the 8 materials tested over a broad range of engineering strain rates. The mechanical tests at numerous strain rates provided an understanding of the strain rate sensitivity of the polymers and was used for material model validation.
