摘要: Abstract In this article, an analytical model is derived to investigate the in-plane homogenized stress-strain relationship of adhesively bonded commercial hexagonal honeycomb core under large deformation. The incorporates some advanced features cell such as wall curvatures, node bond adhesive layers, and fillets at intersections in analysis. Nonlinear results fiberglass/phenolic predicted by are compared with test data well predictions from finite element models (FEMs) both real idealized (without modeling adhesive) cells effects adhesive. Predictions good agreement FEM cell. Homogenized properties obtained infinitesimal strains several literature. Adhesive peel stress also calculated FEM.
