NFL helmet challenge DfAM eSeries: Control the collapse - Architected materials for impact absorption

When it comes to absorbing an impact, something's gotta give. Generally, that is one of two things: a protective structure like a helmet (which is hopefully present), or the sensitive object being protected (e.g. a person's body or head).

Lattices and cellular structures offer a huge design space to tune and optimize this deformation capability, and therefore the energy absorption capacity.

In this presentation, Jonathan Harris, Senior Application Engineer at nTop, distills a few key underlying variables in this endless design space, to help engineers get the most out of their energy-absorbing structures.
