“…The parameter µ = µ 2 /µ 1 is chosen from the interval 0 < µ < 3.5. The relative magnetic permeability µ rj (j = 1, 2) varies within the interval 10-10 6 for the magnetosoft ferromagnetic materials (see Shindo, 1978Shindo, , 1983Hasanyan et al, 1988Hasanyan et al, , 1997Bagdasarian and Hasanyan, 2000;Liang et al, 2002;Lin and Lin, 2002). We write K ++ 2 for the stress intensity factor K ++ 2 = K + 2 (ν 1 , ν 2 , µ, 0) for the purely elastic case (in the absence of magnetic field, i.e.…”
