Assuming smoothness conditions on the data, the solution u can be written as a sum of a singular part u∗ and regular one u − u∗ satisfying the following properties: u∗ = KI uI + KI I uI I , (2) u − u∗ ∈ H2+m ( ), (3) for some integer m ≥ 0 such that (in particular) g ∈ Hm ( ). In the deﬁnition of u∗ , the constants KI , KI I are the so-called stress intensity factors and the displacements uI , uI I denote the opening modes of the crack. For a bi-dimensional crack [12, 13]: uI = 1 E r (1 + ν) 2π cos θ2 (3 − 4ν − cos θ ) uI I = 1 E r (1 + ν) 2π sin θ2 (γ + 2 + cos θ ) , sin θ2 (3 − 4ν − cos θ ) sin θ2 (γ − 2 + cos θ ) , (4) (5) 30 E.
