Abstract

? In this study, an experimental investigation, an analytical analysis and a numerical model of a typical 3-point bending test on copper honeycomb multi-layer sandwich panel are proposed. The copper honeycomb core is modelled as a single solid and multi-layer of equivalent material properties. Analytical and numerical (finite element) homogenization approaches are used to compute the effective properties of the single honeycomb core and analytical homogenization of the multi-layer one. The results obtained by numerical simulation (finite element) of 3-point bending are compared with the experimental results of a copper honeycomb core a stainless steel chosen a face sheet and copper is a core material. Honeycombs are most often an array of hollow hexagonal cells with thin vertical walls Copper Honeycomb is low density permeable material with numerous applications.
