Head injuries in an explosion occur as a result of a sudden pressure changes (e.g. shock-blast) in the atmosphere (primary injury), high velocity impacts of debris (secondary injury) and people being thrown against the solid objects (tertiary injury) in the field. In this thesis, experimental and numerical approaches are used to delineate the intracranial loading mechanics of both primary (blast) and tertiary injuries (blunt).
The blast induced head injuries are simulated using a fluid-filled cylinder. This simplified model represents the head-brain complex and the model is subjected to a blast with the Friedlander waveform type of loading. We measured the …

Improvised explosive devices (IEDs) have become a primary weapon in conflicts against US and allied forces. Improvements in body armor and medicine have increased the survivability of such events. These factors have caused an increase in traumatic brain injury (TBI) and mild traumatic brain injury (mTBI) induced by primary blast waves. Injury mechanisms caused from primary blast waves are not clearly understood or defined. How primary blast waves interact with materials or between narrow gaps found between helmet pads is not known. Two novel test fixtures were developed to provide a basic understanding of these two issues.
The first fixture …

Brain injury cases in military personnel exposed to improvised explosive devices (IED) in combat have been on the rise. In Iraq and Afghanistan improved helmets and body armor are not enough protection against blast wave threats. The United States military are sponsoring researchers and scientists around the globe to find the associations between pressure waves and traumatic brain injury (TBI).
Lack of accurate data and blast wave exposure information in returning soldiers has slowed the innovation needed to effectively diagnose TBI and other related brain injury as a result of pressure waves. More detailed data will be required to gain …
