| description | ObjectiveNegative Poisson’s ratio materials are widely used in various fields because of their unique properties of expansion in tension and contraction in compression.MethodsA honeycomb material with negative Poisson’s ratio was obtained by equal biaxial compression of the two-dimensional Voronoi model, and the effects of different compression ratios on its static tensile/compressive mechanical properties were studied by numerical simulation.ResultsThe results show that the tensile and compressive stress-strain curves of the two-dimensional negative Poisson’s ratio honeycomb prepared by the above method have typical "three-stage" deformation characteristics of porous materials, and show significant tensile and compressive strength asymmetry. Under uniaxial tension, the material shows obvious negative Poisson’s ratio phenomenon. With the increase of compression ratio, the elastic modulus and elastic Poisson’s ratio gradually decrease, and the yield strength and platform stress gradually increase. With the gradual increase of tensile strain, the plastic Poisson’s ratio of the material changes from negative to zero and then to positive. However, due to the mutual contact between the inner edges of the material, the inward deformation of the material is limited. Therefore, the material exhibits positive Poisson’s ratio behavior under uniaxial compression, and its elastic modulus, yield strength, elastic/plastic Poisson’s ratio and platform stress increase with the increase of compression ratio. In addition, the negative Poisson’s ratio material is anisotropic in tension and isotropic in compression. |
