Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Abstract Architected materials achieve unique mechanical properties through precisely engineered microstructures that minimize material usage. However, a key challenge of low‐density is balancing high stiffness with stable deformability up to large strains. Current microstructures, which employ slender elements such as thin beams and plates arranged in periodic patterns optimize stiffness, are largely prone instabilities, including buckling brittle collapse at low This here addressed by introducing new class aperiodic architected inspired quasicrystalline lattices. Beam networks derived from canonical patterns, the Penrose tiling two dimensions icosahedral quasicrystals (IQCs) three dimensions, shown create stiff, stretching‐dominated topologies non‐uniform force chain distributions, effectively mitigating global instabilities observed designs distributed localized instabilities. Numerical experimental results confirm effectiveness these combining strains, representing significant advancement development metamaterials for applications requiring impact resistance energy absorption. These demonstrate potential deterministic quasi‐periodic bridge gap between random structures, while branching toward uncharted territory property space materials.
