Honeycomb structure of the honeycomb remains roughly constant. Once a certain strain is reached, the material will begin to undergo densification as further compression pushes the cell walls together. Out of-plane loading: Under out-of-plane loading, the out-of-plane Young’s modulus of a regular hexagonal honeycombs is proportional to the relative density of the honeycomb. The elastic buckling stress is proportional to (t/L) while the plastic buckling stress is proportional to (t/L). The shape of the honeycomb cell is often varied to meet different engineering applications. Shapes that are commonly used besides the regular hexagonal cell include triangular cells, square cells, and circular-cored hexagonal
Wax foundation Wax foundation Wax foundation or honeycomb base is a plate made of wax with the base of the honeycomb. It is used in beekeeping to give the bees a foundation on which they can build the honeycomb. Wax foundation is considered one of the most important inventions in modern beekeeping. Wax foundation was invented by German Johannes Mehring in 1857, a few years after Langstroth designed and patented the Langstroth hive on October 5, 1852. Mehring's wax foundation had only the bottom of the cells, and today's base with the foundation of the cells was invented by US beekeeper Samuel
