Abstract: | We give a sharp (optimal) regularity theory of thermo-elastic mixed problems. Our approach is by P.D.E. methods and applies to any space dimension and, in principle, to any set of boundary conditions. We consider two sets of boundary conditions: hinged and clamped B.C. The original coupled P.D.E. system is split into two suitable uncoupled P.D.E. equations: a Kirchoff mixed problem and a heat equation, whose delicate, optimal regularity is available in the literature. Ultimately, the original problem with boundary non-homogeneous term is reduced to the same problem, however, with homogeneou B.C. and a known ‘right-hand term’ in the equation, which is easier to analyze. |
