【摘要】 应用东北大学开发的材料破坏过程分析软件MFPA2D,以预置于不同岩石中的裂纹为研究对象,通过对带有预裂纹不同拼接岩板单轴压缩数值实验,探讨了预裂纹在具有不同岩性的岩石中扩展、相互作用直至贯通过程的破坏机制。模拟结果与相应的实验结果较为一致。更多还原

【Abstract】 Multi-crack are preset in the plates which consist of different rocks;and numerical tests are performed on the specimen under uniaxial compression by using MFPA 2D (material failure process analysis)Code recently developed.The crack propagation and coalescence processes in different rock media are studied.The numerical results have shown good agreement with those of other experiments.更多还原
