Abstract

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
