... was used to establish parallel bond models with different micro parameters (tensile strength, cohesion and bond gap). The uniaxial compression test of coal and rock samples was carried out, and the influence of different parameters on the deformation and uniaxial compressive strength of samples...

... on the uniaxial compressive strength of conglomerate (Sonmez et al., 2006). Li et al., 2013, conducted numerical simulations by RPFA2D to investigate the effects of closure pressure, gravel size, and gravel shape on the propagation of fractures. And they divided the propagation mode of fractures into five types...

... to determine the peak uniaxial compressive strength (UCS). For the second set of samples, the first strain rate was applied to the sample up to a predetermined load, and then the second strain was initiated to find out the influence of multiple loading rates on the UCS of rock samples. 1. INTRODUCTION Geo...

... is first validated by comparing numerical results with published experimental data. Numerical results highlight the FTC deterioration of the uniaxial compressive strength and Young s modulus of rock specimens. We establish exponential correlations between the freeze-thaw cycle number and the rock s...
