Finite element analysis of dynamic crushing behaviors of closed-cell foams based on a tetrakaidecahedron model
基于十四面体模型的闭孔泡沫材料动态力学性能的有限元分析
SC cell was treated in 3-dimension as a tetrakaidecahedron with 14-surfaces including six quadrangles and eight hexagons.
方法用有限元方法离散偏微分方程的差分格式,将角质层的角蛋白细胞近似为物理学上经典的由6个四边形和8个六边形围成的三维十四面体结构,同时将角蛋白细胞间的脂质体视为十四面体结构的一部分,离散其相应的单元网格。
Particularly the detailed analysis of the topological geometry attribute on a fourteen surfaces structure-tetrakaidecahedron was fulfilled.
为了采用偏微分方程求解流体的多层复杂几何结构的渗透性质,本文提出了一种多层三维复杂几何结构的网格拆分方法,尤其对多层结构中的核心——1个由6个四边形和8个六边形围成的十四面体(即物理学上经典的Tetrakaidecahedron体)的空间拓扑几何结构进行了详细的分析。
