Abstract

Blunt trauma evaluation plays vital role in the design, development and validation of any non-lethal ammunition. Foam nosed projectiles are one among of the commonly used and most popular non-lethal ammunition. An extensive study to evaluate the effect of energy absorbing mechanisms (collapsible Aluminum foiled structure, Collapsible Aluminum cylinder with slots and corrugations etc) on the blunt thoracic trauma caused by a typical foam projectile was conducted. For this study, finite element model of the thorax of the 50% percentile male deformable Hybrid III dummy was used as the target. CAE simulation iterations by impacting the target with a typical foam nosed projectile at 75-100 m/s (with an increment of 5 m/s) were carried out. Similar impact cases were carried out by using foam projectile with the energy absorbing mechanisms. In this paper, force-time responses obtained from the numerical simulations were analyzed and effect of the energy absorbing mechanisms on the blunt thoracic trauma was discussed.
