TL;DR: In this paper, the in-plane dynamic crushing of two-dimensional honeycombs with both regular hexagonal and irregular arrangements was investigated using detailed finite element models, and three distinct crushing modes for honeycomb with a constant relative density: quasi-static, transition and dynamic.

TL;DR: In this article, the authors investigated the mechanical behavior of two-dimensional hierarchical honeycomb structures using analytical, numerical and experimental methods, and provided insight into the role of structural organization and hierarchy in regulating the mechanical behaviour of materials, and new opportunities for developing lowweight cellular structures with tailorable properties.

TL;DR: A series of analytical relationships is presented to predict the mechanical properties and response of open three-dimensional Voronoi tessellation of face-centered cubic structures called rhombic dodecahedrons.

TL;DR: It is shown that, unlike unpressurized shells, the relationship between force and displacement demonstrates two linear regimes, and it is inferred that the internal osmotic pressure of yeast cells may be regulated in response to changes in the osmosis pressure of the external medium.

TL;DR: In this paper, the authors investigated the properties of functional graded Voronoi structures as a function of density gradient and found that the overall effective elastic modulus and yield strength of structures increased with increasing the density gradient.
