Figure 7 : Ratio of the damaged zone according to the crack tilt.

(a) (b) (c) Figure 8 : Damaged zone for a circular patch (a) θ = 15 o , (b) θ = 45 o and (c) θ = 75 o . The Fig. 9 shows the variation of the ratio of the damaged zone as a function of the inclination. Whatever the value of the inclination of the crack, it is noted that the critical value D RC has not been reached, and that the increase in the crack inclination directly leads to the increase of D R .
