Abstract

Continuum models of regular hexagonal aluminum honeycomb cores are evaluated by finite element analysis. The evaluation is based on the comparison of total in-plane and out-of-plane reaction forces determined by the finite element analyses of the sandwich panels with the actual honeycomb core geometry and with the existing equivalent core models.
