Abstract
A system and method for designing a helmet to reduce mild traumatic brain injury sustained by a user during primary or secondary head impact include modeling a helmeted head including a head, brain, and helmet using a finite element computer model, the finite element computer model including material properties for the head, brain structures, and helmet and estimating at least intracranial pressure, brain strain and strain rate in response to an impact; and selecting at least one of a helmet cushion material and helmet shell material to limit at least one of intracranial pressure, brain strain and strain rate to a corresponding threshold for an associated impact.
