文摘
- •
Surrogate model-based design optimization was performed on a football helmet facemask to reduce brain injury metrics.
- •
Differences in brain response as high as 194% were observed by simply changing facemask topology.
- •
Peak head acceleration was not a good indicator of pressure or shear strain in the brain.
- •
Maximum tensile pressure and maximum shear strain in the brain were reduced 7.5% and 39.5%, respectively.
