Stress Evolution in Punch-Through Shear Tests: A Numerical Study Based on Discrete Element Method
The discrete element method is adopted to investigate the failure process in punch-through shear tests. The numerical tests agree well with the laboratory tests on crack propagation sequence and the influence of confining stress on effective shear fracture toughness. More importantly, the numerical...
