A gyroid minimal surface, coloured to show the Gaussian curvature at each point 3D model of a gyroid unit cell. A gyroid is an infinitely connected triply periodic minimal surface discovered by Alan Schoen in 1970. [1] [2] It arises naturally in polymer science and biology, as an interface with high surface area.
Early research (Bathurst and Jarrett, 1988) [13] found that cellular confinement reinforced gravel bases are "equivalent to about twice the thickness of unreinforced gravel bases" and that geocells performed better than single sheet reinforcement schemes (geotextiles and geogrids) and were more effective in reducing lateral spreading of infill under loading than conventional reinforced bases.
A major factor in choosing the right mesh is the length ratio (length vs honeycomb cell diameter) L/d. Length ratio < 1: Honeycomb meshes of low length ratio can be used on vehicles front grille. Beside the aesthetic reasons, these meshes are used as screens to get a uniform profile and to reduce the intensity of turbulence. [27]
Cubic honeycomb. In geometry, a honeycomb is a space filling or close packing of polyhedral or higher-dimensional cells, so that there are no gaps. It is an example of the more general mathematical tiling or tessellation in any number of dimensions. Its dimension can be clarified as n-honeycomb for a honeycomb of n-dimensional space.
Stereo image of gyroid unit cell by Alan Schoen (2014) Alan Schoen is best known for discovering (while working at NASA) a minimal surface that he named the gyroid. [6] [7] [8] The name stems from the impression in the gyroid's structure that each continuous channel in the array, along different principal crystallographic axes, has connections to additional intersecting channels, which ...

The trapezo-rhombic dodecahedral honeycomb is a space-filling tessellation (or honeycomb) in Euclidean 3-space. It consists of copies of a single cell, the trapezo-rhombic dodecahedron . It is similar to the higher symmetric rhombic dodecahedral honeycomb which has all 12 faces as rhombi.
