“…In the progressive (low

\overset{ρ}{true}

σ_{normalc} ~ {\overset{ρ}{true}}^{1.34}

and

E_{normalc} ~ {\overset{ρ}{true}}^{1.43}

, respectively. This is in excellent agreement with finite element simulations (Figure b; Figure S3, Supporting Information) as well as the reported theoretical behavior of shell‐based spinodal topologies . In the same relative density range, all other high‐strength lattice materials have considerably less efficient scaling behavior, with scaling exponents of 1.9–2.5 .…”

“…Shell‐based topologies have a mean curvature close to zero everywhere, which facilitates a uniform strain distribution upon loading . This unique topological feature has also been shown to impart them good strength and stiffness . A particular class of shell‐based architectures are spinodal topologies, which can be produced by spinodal decomposition of two phases followed by removal of one phase, coating of the interface and subsequent removal of the second phase .…”

“…A particular class of shell‐based architectures are spinodal topologies, which can be produced by spinodal decomposition of two phases followed by removal of one phase, coating of the interface and subsequent removal of the second phase . Compared to periodic designs, their stochastic nature provides decreased imperfection sensitivity as well as fully isotropic behavior, while still offering near‐uniform strain distribution upon loading . Thus, shell‐based spinodal topologies are ideal candidates for combining high energy absorption capability, strength, and stiffness at low weight.…”

“…Although beam‐based lattices can be designed to possess high‐strength, their sharply intersecting beams cause stress concentrations at the lattice nodes which serve as crack propagation sites, potentially causing the generally observed catastrophic failure. By contrast, spinodal topologies are free of pronounced stress concentrations, and as demonstrated above, crack propagation can be tailored by design, resulting in a very progressive failure mechanism. The high specific strength of nanoscale glassy carbon compared to most bulk materials may explain the superior energy absorption capability of our nanospinodals compared to larger‐scale periodic shell‐based structures with gyroid, p‐Schwarz or other triply minimal surface topologies .…”

Nanolattices are promoted as next‐generation multifunctional high‐performance materials, but their mechanical response is limited to extreme strength yet brittleness, or extreme deformability but low strength and stiffness. Ideal impact protection systems require high‐stress plateaus over long deformation ranges to maximize energy absorption. Here, glassy carbon nanospinodals, i.e., nanoarchitectures with spinodal shell topology, combining ultrahigh energy absorption and exceptional strength and stiffness at low weight are presented. Noncatastrophic deformation up to 80% strain, and energy absorption up to one order of magnitude higher than for other nano‐, micro‐, macro‐architectures and solids, and state‐of‐the‐art impact protection structures are shown. At the same time, the strength and stiffness are on par with the most advanced yet brittle nanolattices, demonstrating true multifunctionality. Finite element simulations show that optimized shell thickness‐to‐curvature‐radius ratios suppress catastrophic failure by impeding propagation of dangerously oriented cracks. In contrast to most micro‐ and nano‐architected materials, spinodal architectures may be easily manufacturable on an industrial scale, and may become the next generation of superior cellular materials for structural applications.

Materials based on minimal surface geometries have shown superior strength and stiffness at low densities, which makes them promising continuous-based material platforms for a variety of engineering applications. In this work, it is demonstrated how these mechanical properties can be complemented by dynamic functionalities resulting from robust topological guiding of elastic waves at interfaces that are incorporated into the considered material platforms. Starting from the definition of Schwarz P minimal surface, geometric parametrizations are introduced that break spatial symmetry by forming 1D dimerized and 2D hexagonal minimal surface-based materials. Breaking of spatial symmetries produces topologically non-trivial interfaces that support the localization of vibrational modes and the robust propagation of elastic waves along pre-defined paths. These dynamic properties are predicted through numerical simulations and are illustrated by performing vibration and wave propagation experiments on additively manufactured samples. The introduction of symmetry-breaking topological interfaces through parametrizations that modify the geometry of periodic minimal surfaces suggests a new strategy to supplement the load-bearing properties of this class of materials with novel dynamic functionalities.

Tensegrity Metamaterials: Toward Failure‐Resistant Engineering Systems through Delocalized Deformation

et al. 2021

Failure of materials and structures is inherently linked to localized mechanisms, from shear banding in metals, to crack propagation in ceramics and collapse of space‐trusses after buckling of individual struts. In lightweight structures, localized deformation causes catastrophic failure, limiting their application to small strain regimes. To ensure robustness under real‐world nonlinear loading scenarios, overdesigned linear‐elastic constructions are adopted. Here, the concept of delocalized deformation as a pathway to failure‐resistant structures and materials is introduced. Space‐tileable tensegrity metamaterials achieving delocalized deformation via the discontinuity of their compression members are presented. Unprecedented failure resistance is shown, with up to 25‐fold enhancement in deformability and orders of magnitude increased energy absorption capability without failure over same‐strength state‐of‐the‐art lattice architectures. This study provides important groundwork for design of superior engineering systems, from reusable impact protection systems to adaptive load‐bearing structures.
