Team creates new ultralightweight, crush-resistant tensegrity metamaterials

phys.org
  • Tensegrity is a century old design principle combining a flexible mesh with isolated rigid bars in order to delocalize deformations.
  • Thanks to this, the material can’t get destroyed in a chain reaction of locally confined damage (like when ceramics break from an initial small crack).
  • This is the first ever physical demonstration of tensegrity metamaterials.
  • It shows a 25 times improvement in deformability, and orders-of-magnitude improvement in energy absorption compared to state-of-the-art materials.
  • The material could have a wide array of potential engineering applications.
