ADVANCES IN FRACTURES OF PARTICLES WITH DISTINCT ELEMENT METHOD

  • 摘要: 颗粒离散元法(distinct element method,DEM)是被不同学科和工程领域广泛应用的方法,各学科结合各自的理论基础和研究范围,对颗粒离散元法进行改进、完善,因此各学科间的发展各有侧重,可进行相互借鉴。本文针对颗粒离散元法中有关"颗粒碎裂"这一基本问题进行介绍,如:颗粒破裂准则、颗粒碎裂与破碎动力学关系、宏观颗粒的发展、块体碰撞损伤与破裂等方面的研究情况,为岩石工程领域的岩石颗粒破碎研究提供参考。同时,对颗粒离散元法的发展概况、DEM基本原理做了简单的介绍,并对我国颗粒离散元法在地质工程、岩土工程领域的研究及应用情况作了简单的评述。
