摘要
采用动力接触法建立了高压水射流破碎岩石过程的计算模型。应用动力瞬态非线性有限元法,对射流冲击岩石时射流冲击动载的变化、岩石破碎区域的扩展过程进行了数值研究。并对非线性动力冲击有限元数值求解的几种方法做了讨论。
A computational model of rock fragmentation by high pressure jet was established with dynamic contact method. Based on dynamic transient non-linear finite element method, the change of jet impact dynamic load and development of rock crash by high pressure jet was numerically studied.
