Dynamic Analysis Of Honey Comb Structure

A honeycomb structure is a geometric arrangement of hexagonal cells, similar to the pattern foundina beehive. In engineering and materials science, honeycomb structures are typically composedoflightweight materials arranged in a hexagonal grid, creating a rigid and strong structure withminimalmaterial usage. These structures are known for their high strength-to-weight ratio, makingthemadvantageous in various applications. Materials like aluminum, composites, and even paper canbeshaped into honeycomb structures. The design mimics the efficiency seen in natural honeybeehives,wherehexagonalcellsprovide strengthandstability withminimal use ofresources.Inthis,weareanalysingtheperforationofcompositesandwichstructuresunderhigh-velocityimpact.we areusing a three-dimensional finite element model modelled in Creo and implementing in Ansystosimulate sandwich panels with carbon/epoxy skins and an aluminium honeycomb core.
