SUMMARY:Optimized shock-protecting microstructures
DESCRIPTION:Zizhou Huang, Daniele Panozzo, and Denis Zorin (New York Unive
 rsity)\n\nMechanical shock is a common occurrence in various settings, the
 re are two different scenarios for shock protection: catastrophic protecti
 on (e.g. car collisions and falls) and routine protection (e.g. shoe soles
  and mattresses). The former protects against one-time events, the latter 
 against periodic shocks and loads. Common shock absorbers based on plastic
 ity and fracturing materials are suitable for the former, while our focus 
 is on the latter, where elastic structures are useful. Improved elastic ma
 terials protecting against shock can be used in applications such as autom
 otive suspension, furniture like sofas and mattresses, landing gear system
 s, etc. Materials offering optimal protection against shock have a highly 
 non-linear elastic response: their reaction force needs to be as close as 
 possible to constant with respect to deformation.  \n\nIn this paper, we u
 se shape optimization and topology search to design 2D families of microst
 ructures approximating the ideal behavior across a range of deformations, 
 leading to superior shock protection. We present an algorithmic pipeline f
 or the optimal design of such families combining differentiable nonlinear 
 homogenization with self-contact and an optimization algorithm. We validat
 e the effectiveness of our advanced 2D designs by extruding and fabricatin
 g them with 3D printing technologies and performing material and drop test
