Question

How to calculate the lattice parameter of honeycomb structure?

Answer 1

Honeycomb structuresare natural or man-made structures that have the geometry of ahoneycombto allow the minimization of the amount of used material to reach minimal weight and minimal material cost. The geometryof honeycomb structures can vary widely but thecommon feature of all such structures is an array of hollow cells formed between thin vertical walls. The cells are oftencolumnarandhexagonalin shape. A honeycomb shaped structure provides a material with minimal density and relative high out-of-planecompression propertiesand out-of-planeshear 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. Honeycomb materials are widely used where flat or slightly curved surfaces are needed and their highSpecific strengthis valuable. Theyare widely used in theaerospaceindustry for thisreason, and honeycomb materials in aluminum, fibreglass and advanced composite materials have been featured in aircraft and rockets since the 1950s. They can also be found in many otherfields, from packaging materials in the form of paper-based honeycomb cardboard, to sporting goods like skis and snowboards.
