To date, the underlying mechanisms of blast induced traumatic brain injury (bTBI) are still not fully understood. Biomechanical responses such as intracranial pressure (ICP), head linear accelerations, and head angular velocities measured in live animals can provide crucial information on injury response and tolerance of the brain exposed to blast. However, the acquisition of these data, using large animal test subjects, in open-field blasts is a major undertaking and, there are only limited biomechanical data available from shock tube testing which cannot fully simulate an open field blast. In this study, swine subjects were exposed to free-field blasts generated by 3.6 kg of C4 charge. Three incident overpressures (IOP) were generated by placing the charge at three standoff distances from the swine. Five swine were exposed to a total of 19 blasts, during which ICP, 3D linear acceleration, and 3D angular velocity were recorded simultaneously throughout the blast. A 4th order phaseless low pass Butterworth software filter was applied to the data.
