“…7) and (2.8) and taking into account the homogeneous contact conditions on S we get b , E ' ( U ' , u') dx + IQ,T'(u2, u') dx = 0.Therefore, according to the relations (2.9) and (2.10) it holds thatDkuY + DjuT = 0, k, j = 1,2, 3, m = 1, 2. These equalities yield [17] um(x) = [am x x] + b", x E Om, m = 1,2, (2.1 1)where am and 6"' are three-dimensional constant vectors.From the regularity of the vector u2 at infinity it follows a2 = b2 = 0 that is Now equations (2.5) for u' imply that (u')+ = 0 on S and the uniqueness theorem for the interior Dirichlet (displacement) problem gives u ' ( x ) = 0, x E fil Theorem 2.2.…”
