Mechanical Properties of Tissue in Living Humans

Abstract

To calculate the expected risk of significant injury (RSI) to individuals struck with blunt trauma munitions, the Joint Non-Lethal Weapons Program (JNLWP) has developed computational finite element models of the human to simulate the impact and predict the response of a living person. These models were developed and validated using biomechanical data collected during testing of post-mortem human surrogates (PMHS). The mechanical properties of PMHS tissue are known to differ from those of the live human, especially muscle and other soft tissues, limiting the biofidelity of existing models. Our research group, composed of AMERICAN SYSTEMS and the University of Virginias Center for Applied Biomechanics (UVA-CAB), examined the difference in material properties between the soft tissue of PMHS and live humans in various states of muscle activation for the purpose of providing JNLWP with data intended to improve the biofidelity of their human body models.
