Auxetic metamaterials for impact protection
van den Boom, S.J.
van Veen, D.
This work investigates the impact protection properties of auxetic metamaterial lattices for impact velocities between 40 and 100 m/s, in a 1D impact scenario. After successful previous experiments and simulations with lower impact velocities and nylon samples, we now investigate whether or not the auxetic properties of such metamaterial are retained under higher impact velocities using metal samples. The aim is to use auxetic metamaterials in the design of impact protection concepts. In order to qualitatively illustrate the effect of the auxetic lattice, numerical simulations of the auxetic lattice are compared to a non-auxetic lattice of similar density. The numerical simulations in this extended abstract are performed in Abaqus, and are used to design the test set up that will be used to validate the model.
