  2. Honeycomb structure - Wikipedia

    en.wikipedia.org/wiki/Honeycomb_structure

    A honeycomb-shaped structure provides a material with minimal density and relative high out-of-plane compression properties and out-of-plane shear properties. [1] Man-made honeycomb structural materials are commonly made by layering a honeycomb material between two thin layers that provide strength in tension. This forms a plate-like assembly.

  3. Ha-ha - Wikipedia

    en.wikipedia.org/wiki/Ha-ha

    Comparison of a ha-ha (top) and a regular wall (bottom). Both walls prevent access, but one does not block the view looking outward. A ha-ha (French: hâ-hâ [a a] ⓘ or saut de loup [so də lu] ⓘ), also known as a sunk fence, blind fence, ditch and fence, deer wall, or foss, is a recessed landscape design element that creates a vertical barrier (particularly on one side) while preserving ...

  4. Honeycomb - Wikipedia

    en.wikipedia.org/wiki/Honeycomb

    The closed ends of the honeycomb cells are also an example of geometric efficiency, though three-dimensional. [5] The ends are trihedral (i.e., composed of three planes) sections of rhombic dodecahedra, with the dihedral angles of all adjacent surfaces measuring 120°, the angle that minimizes surface area for a given volume.

    en.wikipedia.org/wiki/Glossary_of_landforms

    Honeycomb weathering – Form of cavernous weathering and subcategory of tafoni; Impact crater – Circular depression in a solid astronomical body formed by the impact of a smaller object; Joint valley – Landscape originates from the erosion of joints in the bedrock, leaving out small plateaus or ridges in between. Common in Fennoscandia.

  6. Order-5 hexagonal tiling honeycomb - Wikipedia

    en.wikipedia.org/wiki/Order-5_hexagonal_tiling...

    The rectified order-5 hexagonal tiling honeycomb, t 1 {6,3,5}, has icosahedron and trihexagonal tiling facets, with a pentagonal prism vertex figure. It is similar to the 2D hyperbolic infinite-order square tiling, r{∞,5} with pentagon and apeirogonal faces. All vertices are on the ideal surface.

  7. Hypercubic honeycomb - Wikipedia

    en.wikipedia.org/wiki/Hypercubic_honeycomb

    In geometry, a hypercubic honeycomb is a family of regular honeycombs (tessellations) in n-dimensional spaces with the Schläfli symbols {4,3...3,4} and containing the symmetry of Coxeter group R n (or B ~ n–1) for n ≥ 3.

  8. Waffle fabric - Wikipedia

    en.wikipedia.org/wiki/Waffle_fabric

    Waffle fabric, also known as honeycomb fabric, has raised threads that form small rectangles. It can be made by either weaving or knitting. Waffle weave is a further exploitation of plain weave and twill weave which produces a three-dimensional effect. The combination of warp and weft floats creates the structure.

  9. 5-cubic honeycomb - Wikipedia

    en.wikipedia.org/wiki/5-cubic_honeycomb

    The 5-cubic honeycomb can be alternated into the 5-demicubic honeycomb, replacing the 5-cubes with 5-demicubes, and the alternated gaps are filled by 5-orthoplex facets. It is also related to the regular 6-cube which exists in 6-space with three 5-cubes on each cell. This could be considered as a tessellation on the 5-sphere, an order-3 ...
