Effects of Flaw Geometry on the Fracturing Behavior of Rock-Like Materials Containing Two Arch-Like Parallelogram Flaws

Figure 4

Effects of heterogeneity on the stress-strain curves of specimens containing two preexisting parallelogram flaws. (a) Specimen containing two flaws with the same area (α = β = 45°). (b) Specimen containing two flaws with the same area (α = 45 < β = 60°). (c) Specimen containing two flaws with the same area (α = 45 < β = 75°). (d) Specimen containing two flaws with the same area (α = β = 60°). (e) Specimen containing two flaws with the same area (α = 60 < β = 75°). (f) Specimen containing two flaws with the same area (α = β = 75°).
