摘要/Abstract

摘要： 将非均质性引入虚内键模型中，采用MonteCarlo方法对岩石的非均质性进行赋值，并对岩石试样的动态破坏过程进行数值模拟.结果表明，对于红砂岩而言，当非均质性系数m=5时，虚内键模型的模拟结果与试验结果具有较好的一致性.

Abstract: Heterogeneity was incorporated into the virtual internal bond, Monte-Carlo method was used to evaluate the heterogeneity of rock, and the numerical simulation of dynamic fracture process of rock sample was then done. The simulation results show that for red stone, when the heterogeneity factor m=5, the simulation results of virtual internal bond model agree well with that of the test.

Key words: virtual internal bond (VIB) model, heterogeneity material, Weibull distribution, dynamic fracture process, multiscale
