Dynamic compressive behaviour of cellular materials is crucial to their applications in
energy absorption, ballistic mitigation and blast/impact protection. The recent research …

Spacecraft employ space debris protection shields to mitigate the threat of hypervelocity
impact (HVI) from millimeter-sized (envisioned in centimeters) hazardous space debris …

Voronoi-based architected metamaterials have gained significant recognition as promising
candidates for bone defect repair implants. However, the demanding requirements for …

In this paper, a sandwich panel composed of two metal face sheets and a three-dimensional
(3D) isotropic foam core with negative Poisson's ratio (NPR) was established via FEM. The …

Numerous patterns in nature comprise aesthetics structures and intriguing geometries. The
geometric factors behind these patterns include area, aspect ratio, circularity, orientation …

Biological thin-walled cellular structures have intricate arrangements that facilitate
lightweight and high energy absorption. A prime example is trabecular bone, which …

Considering the lack of abundant experimental data on metal foams under tensile triaxial
loadings, characterization of the yield surface of metallic foam is controversial. In this paper …

Previous researchers have used Voronoi honeycombs to represent and predict the
responses of random foams. Often, a two-dimensional Voronoi honeycomb model is used …

The coral reef rock has a rich porous structure, and establishing an entity model with a
realistic porous structure will do great good to study the mechanical behavior and its …

Although defects cannot be avoided in foam materials, they are barely considered in existing
models where relative density plays a dominating role. Despite sharing the same relative …
