RISAge Does Not Affect the Material Properties of Expanded Polystyrene Liners in Field Used Bicycle Helmets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bicycle helmet foam liners absorb energy during impacts. Our goal was to determine if the impact attenuation properties of expanded polystyrene (EPS) foam used in bicycle helmets change with age. Foam cores were extracted ...
Density Variation in the Expanded Polystyrene Foam of Bicycle Helmets and Its Influence on Impact Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bicycle helmets attenuate head impacts using expanded polystyrene (EPS) foam liners. The EPS density plays a key role in determining the helmet and head response during an impact. Prior pilot work in our lab showed that ...
