Football Helmet Impact
An accurate model of the human cranium and brain was created using Simpleware software after performing an MRI scan of the head of a person, and interpreting the scan to create a geometric model of the head that identifies the shape and location of the skull and the brain. The resulting model was duplicated and positioned face-to-face to obtain the full geometry employed. The impact of the two helmets was simulated with ANSYS Autodyn. The shock waves in the brain and the resulting damage and its location can indicate how and where injury is likely to happen. Design of experiments can help optimize the effectiveness of the helmet by modifying its geometry, and by determining the best location and material for the pads inside the helmet, which are designed to absorb as much of the energy from the impact as possible. In the future, using this same process of simulation-driven product development will result in use-specific helmets that will provide maximum protection and reduce injuries from accidents.
