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. This presentation will distill a few key underlying variables in this endless design space, to help engineers get the most out of their energy absorbing structures.
