Comparing the Performance of American Football Helmet Materials Using Finite Element Simulation
G. Sayde
Concussions remain a major safety concern in the NFL, where player-to-player and head-to-ground impacts can generate substantial head loading. Building on a prior video-analysis project that identified common concussion mechanisms and impact locations, this study used finite element simulations in Autodesk Fusion 360 to evaluate how helmet materials affected force transmission to a simplified headform. Expanded polypropylene (EPP) and expanded thermoplastic polyurethane (E-TPU) padding were compared under low-, medium-, and high-magnitude prescribed frontal, side, and rear loads.
