Preview-type source file of FEBios simulation for cellular structure with closed cubic cells of neo-Hookean material. from Microstructure-based hyperelastic models for closed-cell solids

A comparison between model (continuous line) and simulation (dashed line) of the effective elastic modulus. The cell-core is 10 times softer than the cell walls for structure 1, 20 times softer than the cell walls for structure 2, and 100 times softer than the walls for structure 3. The closed cubical cells and their inclusions are shown at 20\% (right) tension in the vertical direction (colour bar showing the displacement in the same direction).

有效弹性模量的模型曲线（实线）与仿真结果（虚线）对比。其中，结构1的胞核较胞壁柔软10倍，结构2的胞核较胞壁柔软20倍，结构3的胞核较胞壁柔软100倍。右侧子图展示了垂直方向受20%拉伸的封闭立方胞元及其内含物，色标用于表征同一方向的位移。
