Bio-inspired non-self-similar hierarchical microstructures for damage tolerance
نویسندگان
چکیده
Natural composites achieve damage tolerance through a complex microstructure with several hierarchical levels; this has inspired the development of synthetic microstructures, in order to overcome their inherent brittleness. However, while most natural have non-self-similar designs literature use self-similar features. The aim work is therefore investigate whether could be more tolerant than equivalent. Non-self-similar are designed, manufactured and tested; results show that releasing constraint can increase design space composite microstructures lead materials better tolerance, clearer warning before failure, stable failure mechanisms.

Bio-inspired design of hierarchical PDMS microstructures with tunable adhesive superhydrophobicity.
In this paper, bio-inspired PDMS films with different hierarchical microstructures were designed and tunable adhesive super-hydrophobicity was achieved on these films. The adhesive forces between a water droplet and the PDMS film can be adjusted from extremely low (about 8.3 μN) to very high (about 57 μN), and the tunable effect can be ascribed to different wetting states for the water droplets...
متن کاملA nonlinear mechanics model of bio-inspired hierarchical lattice materials consisting of horseshoe microstructures.
Development of advanced synthetic materials that can mimic the mechanical properties of non-mineralized soft biological materials has important implications in a wide range of technologies. Hierarchical lattice materials constructed with horseshoe microstructures belong to this class of bio-inspired synthetic materials, where the mechanical responses can be tailored to match the nonlinear J-sha...
متن کاملBio-inspired self-shaping ceramics
Shaping ceramics into complex and intricate geometries using cost-effective processes is desirable in many applications but still remains an open challenge. Inspired by plant seed dispersal units that self-fold on differential swelling, we demonstrate that self-shaping can be implemented in ceramics by programming the material's microstructure to undergo local anisotropic shrinkage during heat ...
