Artificially-structured materials with negative Poisson's ratio, also known as auxetics, have been the focus of numerous studies over past few decades. In this paper, using a group-theory-based symmetry reduction approach, and based on structure composed rotating rigid triangles, we propose new approach to designing auxetic metamaterials. These metamaterials can be fabricated by variety active or smart structural members that undergo different deformations when subjected external stimulations, e.g. temperature-sensitive in temperature-changing environment. Then, applying controlled stimuli initial structure, obtain desired symmetry-reduced configurations which facilitate programmability ratio. particular, demonstrate programmable metamaterial design starting an C3v symmetry, apply stimulus reduce configuration. The deformed configurations, belong groups C3, CS, C1, enable us program ratio metamaterial. We derive theoretical expressions for associated symmetries, are subsequently verified numerical proof-of-concept Kirigami models. anticipate structures will open up avenues research design.

Customizable stress plateau of lattice structures is sought-after for various engineering applications. In this study, we present a new design strategy to achieve customizable plateau, by introducing the concept embedding self-similar structure in face-centered cubic (FCC) lattice, which thereby constitutes novel FCC hierarchical (FCCH). These FCCH specimens were experimentally validated through quasi-static compression tests, on samples 3D-printed selective laser melting using SS316L. deformation characteristics clarified finite element analysis. The experimental and numerical results consistently show serrated, dual, upward plateaus experienced 0th-order FCC, 1st-order FCCH, 2nd-order structures, respectively. mechanical reinforcements are based stronger interactions between unit cells induced embedded sub-structures. mechanisms dominated order determined horizontal layer-by-layer interaction as well longitudinal buckling collapse. effect geometric configuration that can be customized via optimizing different slave-cell sizes, connecting face-centers components, arranging row layered gradient strategy.
