Overpressure is the primary metric considered when investigating head injuries due to primary blast loading. However, capturing the mechanics of brain motion is necessary to understand the risk of additional injury mechanisms. The Human Surrogate Head Model (HSHM) is used to measure relative brain motion due to live-fire blast loading. Although the initial blast loading resulted in almost no brain motion, the subsequent head rotation generated up to 3 mm of relative brain displacement.
