Numerical Methods for Predicting the Dynamic Crushing Response and Energy Absorption of Composite Aluminum Honeycomb Sandwich Structures
<p>Edgewise crushing responses of composite aluminum honeycomb sandwich structures were predicted using finite element analysis (FEA) software LS-DYNA by modeling the honeycomb as a material with anisotropic properties. The goal of the project was to develop a process for modeling the sandwich …

Identification and Quantification of Nonlinear Behavior in a Disbonded Aluminum Honeycomb Panel using Single Degree-of-Freedom Models
… tests on a damaged specimen are conducted. An aluminum honeycomb sandwich panel is damaged by applying a heat source to the top face sheet. The expansion of the heated area on the face sheet creates a disbond of the face sheet and the honeycomb core. This damaged panel is tested by exciting the …

An experimental investigation of homogeneous fatigue damage in a random short-fiber composite under combined tension-torsion loading
… consisting of SMC composite skins bonded to an aluminum honeycomb core, is proposed. Anisotropic finite element analyses are used to obtain detailed stress and deformation fields in the composite facing and in the core of specimens with optimum geometry. The macroscopic fatigue damage is defined …
