摘要
阐述了岩土类材料的非匀质性特性,以及对岩土类材料弹塑性破裂过程进行数值模拟的分析程序REPFPA,通过8个试样的数值模拟"试验",深入地研究了随机数发生器种子值对岩石试样弹塑性破裂过程的影响.分析结果表明:只要岩石材料力学性质的均质度和其它参数保持不变,随机数发生器种子值对岩石试样弹塑性破裂过程与结果的影响很小.
The properties of anisotropic characteristics of rock-like materials and the elastic-plastic failure process of rock materials are studied by the numerical simulation analysis of the program REPFPA. By means of the numerical simulation ‘test＇ , the influence of the seed for the random number generator on the elastic-plastic failure process of rock specimen is studied in this paper. The conclusion shows that the influence of the seed on the elastic-plastic failure process of rock specimen is very small.
