The Brazilian disc simulation showed reasonable fracture trajectories,
while the tensile strength was slightly larger than the
range of experimental values. The uniaxial tests showed a realistic
fracturing process with fractures coalescing into noticeable fracture
planes. The effect of increasing confining pressure was captured in
both the brittleeductile transition of the stressestrain response
and fracture patterns. Similar to the 2D simulations (Lisjak et al.,
2014b), the failure envelope of the 3D simulations tended to be in
the lower range of the experimental values as the confining pressure
increased. However, unlike the 2D simulations, the 3D results
