Influence of constraints on the effective inplane extensional properties of honeycomb core

This study is focused on the influence of constraints on the extensional in-plane modulus of isolated honeycomb core (HC) and honeycomb core sandwich elements. Such constraints develop when the core is bonded to stiff face sheets. Finite element analysis (FEA) is conducted on unconstrained and constrained HC core under inplane loading. FEA results for the extensional in-plane modulus and Poisson ratios of isolated unconstrained HC core are in …
