Finite element-based optimisation of an elastomeric honeycomb for impact mitigation in helmet liners (2021)
Journal Article
Adams, R., Townsend, S., Soe, S., & Theobald, P. (2022). Finite element-based optimisation of an elastomeric honeycomb for impact mitigation in helmet liners. International Journal of Mechanical Sciences, 214, Article 106920. https://doi.org/10.1016/j.ijmecsci.2021.106920

Finite element simulation was used to analyse the response of an elastomeric pre-buckled honeycomb structure under impact loading, to establish its suitability for use in helmet liners. A finite element-based optimisation was performed using a search... Read More about Finite element-based optimisation of an elastomeric honeycomb for impact mitigation in helmet liners.

Auxetic metamaterial optimisation for head impact mitigation in American football (2021)
Journal Article
Hanna, B., Adams, R., Townsend, S., Robinson, M., Soe, S., Stewart, M., …Theobald, P. (2021). Auxetic metamaterial optimisation for head impact mitigation in American football. International Journal of Impact Engineering, 157, Article 103991. https://doi.org/10.1016/j.ijimpeng.2021.103991

American football has a comparatively high rate of sports-related concussions, despite mitigating strategies including the use of protective helmets. The traditional energy absorbing component, elastomeric foam pads, have limited scope for leveraging...

Investigating the dynamic compression response of elastomeric, additively manufactured fluid-filled structures via experimental and finite element analyses (2021)
Journal Article
Soe, S., Adams, R., Hossain, M., & Theobald, P. (2021). Investigating the dynamic compression response of elastomeric, additively manufactured fluid-filled structures via experimental and finite element analyses. Additive Manufacturing, 39, 101885. https://doi.org/10.1016/j.addma.2021.101885

This study evaluates a fluid-filled, closed-cell lattice as a novel route to reducing peak acceleration in impact environments. A conical structure was designed and built using fused filament fabrication. One structure was manufactured hollow (100% a...
