Buckling of regular, chiral and hierarchical honeycombs under a general macroscopic stress state
An approach to obtain analytical closed-form expressions for the macroscopic 'buckling strength' of various two-dimensional cellular structures is presented. The method is based on classical beam-column end-moment behaviour expressed in a matrix form. It is applied to sample honeycombs with square, triangular and hexagonal unit cells to determine their buckling strength under a general macrosco...

متن کاملPlastic collapse of lattice structures under a general stress state
We present a numerical minimization procedure to determine the macroscopic ‘plastic collapse strength’ of a tessellated cellular structure under a general stress state. The method is illustrated with sample cellular structures of regular and hierarchical honeycombs. Based on the deformation modes found by minimization of plastic dissipation, closed-form expressions for strength are derived. The...

wileyonlinelibrary.com determined by the deformation mechanisms of the ligaments, which buckle under compression at relatively low values of strain. In elasto-plastic porous materials buckling of the beam-like ligaments results in collapse bands that progress at relatively constant stress, providing an efficient energy absorbing mechanism. [ 8–12 ] However, this deformation process cannot be ex...
متن کاملF4-J: Novel Cellular Structures and Sandwich Materials
We investigated the mechanical behavior of two-dimensional hierarchical honeycomb structures using analytical, numerical and experimental methods. Hierarchical honeycombs are constructed by replacing every three-edge vertex of a regular hexagonal lattice with a smaller hexagon. Repeating this process builds a fractal-appearing structure. The stiffness and strength of this structure is controlle...
