| 摘 要： | 认为仓贮散体为服从Mohr—Coulomb屈服准则的理想弹塑性材料 ,散体与仓壁之间的摩擦属于Coulomb摩擦接触问题。就刚性筒仓讨论研究了静态时影响散体进入屈服状态的有关因素 ,提出了一种由散体临界内摩擦角来判断静态散体是否进入屈服状态的方法 ,并用有限元法做了数值模拟

Study of Static Yield of Granular Media in Silo |
| |
| Abstract: | In this paper,the granular media in storage is supposed to be elastic-perfectly plastic behaviour material submitting to Mohr-Coulomb yield criterion,and friction effect between granular media and silo wall is supposed to be Coulomb friction contact problem.The factors influencing the yield state of static graunlar media in rigid silo are studied,a method is proposed which is using granular media critical internal friction angle to identify whether the static granular media is in yield state,and the problems are simulated numerically with finite element method. |
