Sub-structure Geometry Effect on Energy Absorption Ability of Hierarchical Honeycomb under CrushingBy Rakesh Kumar Singh
Abstract: Honeycomb structures are stiff and light weight composite structures which show good energy absorption. Hierarchical honeycomb structures which are bio-inspired innovative form of honeycomb structure, are used for energy absorption applications. The crashworthiness of hierarchical honeycomb structures is function of sub-structure geometry. In the present investigation, crushing of vertex based hierarchical honeycomb with regular polygonal (n=3, 6, 9, 12, 15) and circular substructures is analysed using nonlinear explicit finite element …

Numerical Analysis of Energy Absorption Ability of Polygonal Tubes under CrushingBy Rakesh Kumar Singh, Rakesh Saxena
Abstract: Honeycomb panels are used mostly in energy absorption application in engineering fields such as aerospace, transportation and packaging, etc. Honeycomb panels have good stiffness and are weight efficient structures. The honeycomb core consists of cellular cells. The core cell’s geometry of honeycomb affects the energy absorption ability. In this study, the different geometries of individual cell are analysed in tube form. Tubes of different geometries like square, pentagon, hexagon, octagon, …
