A finite element study of blast traumatic brain injury - biomed 2009.

An idealized finite element human head model was constructed to study biomechanical responses in the brain due to blast overpressure loading from a blast of 10 kg TNT at 1 meter. Brain strain in the coup and contrecoup regions were 4-7x higher than the central region, and high brain strain (15%) large deformation (4 mm) occurred in the brainstem region, indicating a higher probability of injury in the peripheral brain and brainstem regions due to blast overpressure loading.
