On the well-posedness of the equilibrium problem for linear elasticity in unbounded regions

Abstract: In this paper we establish some continuous dependence and uniqueness theorems for equilibrium solutions of the equations of general anisotropic linear elasticity in exterior domains. The method we employ is that of the weight function which we introduced in previous papers. However, this is the first example where the method is applied to a static problem. The above theorems are obtained by allowing the strain to be unbounded at large spatial distances. In some cases, no growth condition is assumed. Moreover, … Show more

“…(See also the references cited in [24].) On specialisation to the exterior problem and the whole space problem our results reproduce or otherwise complement many previous uniqueness theorems including for example, those due to Fichera [4], Galdi and Rionero [7,8] [30] and Wilcox [33]. Some further references are contained in [19].…”

“…Thus, we assume that n ; ayM, vanishes on the (closed) surface 9Q 0 so that We next derive a first-order differential inequality for /(r). Thus, we have from An application of Wirtinger's inequality, together with the arithmetic-geometric mean inequality, then leads to In accordance with the discussion of (3.11), it follows that either /(r) is positive for r ^ r 0 and grows polynomiaily like r Y where ( 5 - 8 ) or I(r) is negative for r>r 0 and decays polynomiaily like r~y.…”
