Mechanical Behavior of 3D Crack Growth in Transparent Rock-Like Material Containing Preexisting Flaws under Compression

Figure 5

Six different patterns of crack coalescence were observed in the 2-flaw specimens. The notion of S, M, and W indicated the shear mode crack coalescence, mixed (shear/tensile) mode crack coalescence, and wing tensile mode crack coalescence (after Wong and Chau [46]).
