论文摘要
最近，Vito Diana，Andrea Bacigalupo，Marco Lepidi和Luigi Gambarotta提出了一种各向异性连续性 - 分子模型，该模型基于对Peridynynamic理论框架中周期性异构库奇材料的线性行为的一对电位。不幸的是，所提出的各向同性材料的模型可能具有零甚至负剪切刚度，例如，硅或德国烯就是这种情况。另外，2D对称性与3D对称性混淆，因此泊松比的限制。
Recently, Vito Diana, Andrea Bacigalupo, Marco Lepidi and Luigi Gambarotta proposed an anisotropic continuum-molecular model based on pair potentials for describing the linear behavior of periodic heterogeneous Cauchy materials in the framework of peridynamic theory. Unfortunately, the proposed model for an isotropic material may have zero or even negative shear stiffness and this will be the case for Silicene or Germanene, for example. In addition, 2D symmetries were confused with 3D symmetries, and hence the limits for the Poisson's ratio.
