摘要
采用基于有限差分的拉格朗日、欧拉相结合的方法,对强荷载冲击下岩石材料破坏进行了数值模拟。在欧拉步中引入模糊方法处理界面,考虑了岩石材料、金属材料、空气的多物质场,给出了模拟结果和几个关键点的压力曲线。对强冲击荷载下岩石破坏研究具有重要的意义。
Numerical simulation of rock failure in strong impact loading was researched based on finite differential scheme combined Lagrangian-Eulerian method. With the consideration of rock materials, metal materials, and material field of air, the materials interface was processed by an Eulerian fuzzy method. The simulation result and some key points of pressure curves were given, which had important significances to study the rock failure in strong impact loading.
