Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy associated with
repetitive head impacts (RHI), but the components of RHI exposure underlying this …

Constitutive modeling is the cornerstone of computational and structural mechanics. In a
finite element analysis, the constitutive model is encoded in the material subroutine, a …

A controversial theory proposes that playing tackle football before the age of 12 causes later
in life brain health problems. This theory arose from a small study of 42 retired National …

Head injury in contact sports can be mitigated, in part, through the enhancement of
protective helmets that may be enabled by detailed finite element models. However, many …

During normal participation in football, players are exposed to repetitive subconcussive
head impacts, or impacts that do not result in signs and symptoms of concussion. To better …

We present a mechanistic data science (MDS) framework capable of building a composite
knowledge database for composite materials design. The MDS framework systematically …

Youth football helmet testing standards have served to largely eliminate catastrophic head
injury from the sport. These standards, though, do not presently consider concussion and do …

The purpose of this study was to compare the effects of wearing older, lower-ranked football
helmets (LRank) to wearing newer, higher-ranked football helmets (HRank) on pre-to post …

Results of a recent experimental study challenge the widely-held belief that modern combat
helmets are more effective at protecting soldiers against concussions. The research shows …

Football helmet testing standards for youth players make use of the same testing protocol for
adult helmets despite research showing differences in head impact exposure between these …
