Fig. 5. K IA /K 0 vs. ψ along the fronts of crescentic radial cracks in arrays of n=1-20 cracks in a vessel of R 0 /R i =1.1 ( ε =100%, a/c=0.6, a/t=0.6).

Fig. 6 . K IA /K 0 vs. ψ along the fronts of crescentic radial cracks in arrays of n=1-20 cracks in a vessel of R 0 /R i =1.2 ( ε =100%, a/c=0.6, a/t=0.6)

one and up to eight cracks is well known (see for example [4]).
