In-plane stiffness of the anisotropic multifunctional hierarchical honeycombs

The anisotropic hexagonal honeycomb is one of the common honeycombs. To increase its in-plane stiffness greatly, in this paper the anisotropic multifunctional hierarchical honeycomb (AMHH) is proposed. It is constructed by replacing the solid cell walls of the original anisotropic hexagonal honeycomb (OAHH) with the equal mass isotropic substructures, triangular or Kagome honeycombs. Two kinds of AMHH structures are proposed. One corresponds to...
