摘要
运用无网格法模拟受压岩体中裂纹的粘接、滑移和张开行为 ,计算了翼形裂纹尖端应力强度因子 ,并对单裂纹和双裂纹的扩展进行了分析模拟 .数值结果表明了计算方法的可行性 .
The meshless method is used to model the state of contact impact, slippage and freedom for cracks in rock structures which compressive stressed are added to, and stress intensity factors are calculated for wing cracks. Single and double crack propagations are analyzed and simulated. The numerical examples show that the method given is effective and feasible.
