Then we use Fourier transform (note that for B sublattice we add another minus sign in the transform): a_{i}=N^{-1/2}\sum_{k}e^{ik\cdot R_{i}}a_{k},\quad a_{i}^{\dagger}=N^{-1/2}\sum_{k}e^{-ik\cdot R_{i}}a_{k}^{\dagger}\\ b_{j}=N^{-1/2}\sum_...
Zhang et al. [15] show that the Young's modulus of the structures is determined solely by the density of the hinges, regardless of the structural orientation or regularity and the failure strain of the honeycomb structure is affected significantly by its lattice size and geometrical regularity. ...
[12] performed in-plane compression and out-of-plan nano-indentation tests on the 3D honeycombs and revealed the localized collapse and significant plastic deformation of the honeycomb lattice, respectively. Daniel et al. [13] found the face yield in sandwich beams with carbon/epoxy facings and ...
