Numerical simulation of crack propagation and coalescence in pre-cracked rock-like Brazilian disks using the non-ordinary state-based peridynamics

In the non-ordinary state-based peridynamics (NOSB-PD), the maximum tensile stress criterion and Mohr-Coulomb failure criterion, which are common stress-based failure criteria in rock mechanics and rock engineering, are applied to distinguish the tensile cracks and shear cracks, respectively. The initiation and propagation and coalescence of one single crack or double cracks in the Brazilian Disk specimens under compressive line loads are...
