颗粒材料中贯入试验的离散元分析

贯入试验已经在岩土工程中得到了广泛的应用,颗粒材料中的贯入过程也可以作为一种煤炭开采方法来进行研究。文章利用离散元数值工具,模拟了颗粒材料中的贯入试验,并从主应力场、速度场、转角场等微观角度对贯入机理进行了探讨。

Discrete Element Analysis for Penetration Test in Granular Materials

Penetration test has been used widely in geotechnical engineering;and penetrating in granular materials can be treated as a new method for coal mining.By performing a series of penetration test in granular materials with Discrete Element Method,this paper has discussed the penetration mechanism from the point of main stress field,velocity field and particle rotation field.
