Design and Numerical Analysis of Corrugated Helmet Under Impact Test

Abstract

In recent years new structures have been developed for sustainability as they are lighter, with less material usage while sustaining their mechanical properties to be utilised in the application. One of these structures is a corrugated structure mainly used in the packaging industry but recently has been recognised by many other applications as the structure is known for its capabilities against shock absorption. In this study, BS6655 was used to evaluate corrugated structure in a helmet while an impact occurs to its front. The dynamic responses of the corrugated helmet were compared with a solid helmet. The results showed that the corrugated helmet has a higher ability to absorb the shock and protect the head from injuries in such impact.
