Developmental framework to validate future designs of ballistic neck protection

Area of Science:

• Biomedical Engineering
• Military Medicine
• Computational Mechanics

Background:

• Neck injuries are a significant cause of mortality and morbidity for UK servicemen in Afghanistan.
• Existing body armor designs require optimization to mitigate penetrating trauma from explosive fragments.

Purpose of the Study:

• To develop a comprehensive framework for simulating penetrating neck injuries.
• To create a validated three-dimensional numerical model of the neck for injury simulation.
• To inform the design of improved body armor and protective garments.

Main Methods:

• Convening an interdisciplinary consensus group of surgeons and scientists.
• Analyzing mortality and morbidity data.
• Characterizing explosive fragments and body armor materials.
• Developing a 3D numerical neck model incorporating critical cervical structures.
• Mapping fragment entry sites and simulating wound tracts.

Main Results:

• A developmental framework for simulating penetrating neck injuries was established.
• A 3D numerical neck model was created to simulate fragment impacts and their effects on neurovascular structures.
• A new ballistic cervical protection shirt has been developed and integrated into early model versions.

Conclusions:

• The developed framework and 3D model provide a robust tool for optimizing body armor and protective gear.
• This interdisciplinary approach facilitates the simulation and understanding of complex injury mechanisms.
• The research contributes to enhanced protection for military personnel against combat-related neck trauma.
