Lattice cellular automata are used to simulate the fracture process of rock samples in uniaxial direct tension. And the influences of heterogeneity, slenderness and size of rock samples on rock failure in direct tension are studied. 利用格构细胞自动机模型模拟了单轴直接拉伸条件下岩石的破坏过程,研究了岩石的非均质性、几何形状(高径比)以及尺寸等对岩石拉伸断裂过程的影响;
