摘要
根据岩石具有非均质和多晶粒的特点,基于Abaqus平台结合泰森多边形原理和Cohesive单元耦合方法,利用Python编程实现了岩石非均质性和多晶体的建模。学生可通过该方法模拟真实岩体的破坏实验并能从细观角度了解岩石断裂时晶粒的破坏特征。该模拟实验补充了传统的岩石力学实验,让学生从细观角度了解岩石的破坏机理,有利于培养学生对岩石力学实验的兴趣,提高学生的学习兴致,还有助于增强学生的创新思维。
According to the characteristics of heterogeneous and multi-grain rock,cohesive coupling method and Tyson polygon principle were applied to cohesive crystal modeling based on Abaqus platform.Through this method,students can simulate the damage of real rock mass and understand the damage characteristics of grain during rock fracture from the mesoscopic perspective.The simulation experiment is a supplement to the traditional rock mechanics experiment,allowing students to understand the damage mechanism of rock from a microscopic perspective,which is conducive to cultivating students’interest in rock mechanics experiment and improving their learning interest,as well as enhancing students’innovative thinking.
