From: The traumatic brain injury mitigation effects of a new viscoelastic add-on liner

(A) Head translational (left) and rotational (right) accelerations for impacts with (red line) and without (black line) the viscoelastic components. Tests were repeated three times, each time on a different helmet; (B) Snapshots of the frontal impact at 7.5 m/s; (C) Improvement in average peak accelerations (rotational and translational) for helmets with viscoelastic components.
