摘要
采用有限元与离散元耦合数值方法开展岩石破碎过程可视化数值模拟。通过对巴西圆盘实验的数值计算,再现了岩石的破坏机理和破坏模式以及岩石裂缝萌生、裂缝扩展以及完全破坏的全过程。分析结果验证了这种数值方法分析岩石变形与破坏过程的可行性。
Visualized numerical simulation the process of rock breaking was carried out by coupled finite-discrete elements method.Through calculating data from Brazilian disc test,the failure mechanisms and failure patterns of rock and the whole failure process of rock from initiation and propagation of cracks to completely breaking were represented.The numerical results showed that the coupled finite-discrete elements method is suitable for the analysis of deformation and failure process of rock.
