202392 · The loading speed of the virtual crushing test is set to 0.01 m/s. The influence of microcracks on the Weibull distribution of crushing strength is considered from three aspects: quantity, location and direction. The characteristic strength of Weibull distribution of basalt particles is positively correlated with the number of microcracks.
