Based on theoretical modeling

finite element simulation and experiment

the shear deformation and failure characteristies of two-dimensional cellular structure were studied

along with the influence of geometric parameters on overall anti-shear property. Through finite element simulation

the shear deformation rule was obtained. A frame shear fixture was used in shear test

whose results were compared with the finite element simulation results. The results show that the failure can attribute to tensile failure and shear failure near the nodes of cell walls

and the damage extends gradually from the edge to the inside. The cell size and cell-wall thickness have significant impact on the shear properties of the material

while the thickness and arrangement angles have little impact on shear properties. The anti-shear property of the hexagonal cellular structure is the largest among hexagonal

re-entrant and semi re-entrant cellular structures.
