The Cholla cactus is a species of cacti that survives in arid environments and produces a
unique mesh-like porous wood. In this article, we present a comprehensive investigation on …

Sponges (phylum Porifera) were among the first metazoans on Earth, and represent a
unique global source of highly structured and diverse biosilica that has been formed and …

The spicules of the deep-sea sponge Euplectella aspergillum show exceptional mechanical
properties due to their unique layered structure. In the present study, a systematic study …

We study the nucleation and development of crack patterns in thin composite fibers under
tension in this work. A fiber comprises an elastic core and an outer layer of a weaker brittle …

Hollow-strut lattices (HSLs) with submillimetre-diameter hollow channels are emerging
lightweight multifunctional metamaterials. High-strength aluminium alloys are highly …

We derive sharp-interface models for one-dimensional brittle fracture via the inverse-
deformation approach. Methods of Γ-convergence are employed to obtain the singular limits …

Biomineralized lattice materials with have high mineral contents (~ 99 wt%), usually"
conceal" multiscale structural arrangements for unique mechanical or functional …

Through thousands of years of evolution, natural biological systems have optimized their
structures to thrive in diverse ecological conditions. Extracting and leveraging the inherent …
