Key Words: Nomex honeycomb, virtual testing, sandwich panel joint, explicit FEA Due to their excellent weight specific stiffness and strength, honeycomb sandwich structures have become a standard material in many lightweight design applications. However, one of the major short comings of sandwich structures in general is their inability to bear localized loads [1]. This weakness is due to the ...

time. Specifically, virtual testing is used to develop a homogenized model for the stress-strain curve of the honeycomb core. The homogenized model is validated by comparison to existing results in the literature as well as to detailed FE models of test specimens. The homogenization approach can be readily applied to other types of cellular core. iv For deflection minimization, results produce ...
