Petrova et alii, Frattura ed Integrità Strutturale, 36 (2016) 8-26; DOI: 10.3221/IGF-ESIS.36.02 17 (e) (f) Figure 7 e, f : The non-dimensional critical load p cr as function of the inclination angle β=β n for two equal edge cracks for different distances d between the cracks: (e) for cracks 1 and 2 (60° ≤ β ≤ 120°) and (f) for cracks 1 and 2 (15° ≤ β ≤ 90°). Two edge cracks with different sizes a 1 =1 and a 2 =0.5. (a) (b) Figure 8 : Stress intensity factors k I and k II as function of the inclination angle β=β 2 (60° ≤ β ≤ 120°) and for β 1 =90° for different distances d between the cracks: (a) for crack 1, (b) for crack 2. Two edge cracks with different sizes a 1 =1 and a 2 =0.5. (a) (b) Figure 9 : Fracture angles ϕ (1) and ϕ (2) as functions of the inclination angle β=β 2 (60° ≤ β ≤ 120°) and for β 1 =90° for different distances d between the cracks: (a) for crack 1, (b) for crack 2. Two edge cracks with different sizes a 1 =1 and a 2 =0.5.
