The peak stress is the strength of particle crushing. Crushing strengths in every group of particles satisfy the Weibull distribution well with an average Weibull modulus of 2.48. In addition, the crushing strengths among different groups of particles shows that the characteristic strengths decrease with the increase of particle size.

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.

1. Introduction. Rock particle material has the characteristics of good compressibility, small deformation, and high shear strength, so it is widely used in railway, highway, tunnel, and other filling projects (Wang et al., 2015).However, when the external force exceeds the bearing limit of rock particles, uneven settlement caused by particle breakage can cause incalculable losses …

ABSTRACT:. Uniaxial compressive strength (UCS) and Brazilian tensile strength (BTS) are widely used in rock engineering. However, preparing standard samples for the strength tests may not always be possible for weak rocks. On the other hand, only rock fragments are available to estimate the rock strength in some cases such as drilling. Therefore, developing …
