Effect of Pre-Existing Symmetrical Cracks on Propagation Behaviors of a Blast-Induced Crack

Figure 13

Simulation results for the specimens with different distances between parallel cracks. (a) S = 20 mm and propagation length: 20.41 mm. (b) S = 30 mm and propagation length: 32.01 mm. (c) S = 40 mm and propagation length: 36.13 mm. (d) S = 50 mm and propagation length: 37.26 mm. (e) S = 60 mm and propagation length: 49.86 mm. (f) S = 70 mm and propagation length: 54.06 mm. (g) S = 80 mm and propagation length: 53.01 mm. (h) S = 90 mm and propagation length: 72.04 mm. (i) No existing parallel cracks and propagation length: 76.28 mm.
