Abstract
Military helmets must constantly evolve to improve head protection against ever changing threats that can be encountered on the battlefield. A helmet’s protection is no longer limited to projectile penetration but also includes its capacity to mitigate behind armour blunt trauma, blunt impact trauma, as well as blast effects. Additionally, facial injuries are becoming a bigger concern and consequently the Advanced Multi-threat Modular Protective Headwear System (AMMPHS) development program incorporates a mandible guard in its design. To assess the effectiveness of a mandible guard an appropriate test methodology and injury based performance criterion must be developed. A specification for the performance of a mandible guard is proposed. Performance levels are based on biomechanical tolerance levels of the mandible region that were identified in the scientific literature. Surrogate headforms and test protocols for assessing performance are evaluated along with appropriate injury tolerance thresholds.
