STUDY ON SHEAR DEFORMATION AND FAILURE CHARACTERISTICS OF TWO-DIMENSIONAL CELLULAR STRUCTURE
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.
