la 中的单元格（假设所有三个方向上螺纹的横截面积相同）将大于实际体积分数。还可以看出，当应力以直角施加到 la 中的单元平面时，比其他方向上更多的螺纹支撑应力。修改后的 GentThomas 模型如图 2 所示。图 2 中的模型不是最通用的可视化模型，但就观察到的各向异性要求而言，该模型被认为是令人满意的。在此模型中，假设螺纹始终具有均匀的横截面，并且各向异性仅是两个方向，即从一个方向看时，单元边界是方形的
cells in la, ( assuming the same area of crosssection for threads in all the three directions) will be larger than the real volume fraction. It can also be seen that more threads support the stress when it is applied at right angles to the plane of the cells in la than in the other directions. A modified GentThomas model is shown in Figure 2. The model in Figure 2 is not the most general one that can be visualized, but as far as the observed anisotropy demands, this model is considered satisfactory. In this model it is assumed that the threads are of uniform cross-sections throughout and the anisotropy is only two directional, i.e. the cell boundary is square when viewed from one
