Vabishchevich, V. M. Vasilieva Numerical Simulation of Thermoelasticity Problem The paper considers the coupled quasi-stationary linear system of equations for temperature and displacement, describing the thermoelastic behavior of the body. The stability estimates of the studied differential problem are presented. For the numerical solution, we approximate our system using the fi nite elements method, and for approximation by time we use the standard two-layer weighted schemes. The discrete problem has proven stable. The results of the numerical simulation of the model problem of thermoelasticity are presented. Key words: strain-stress state, thermoelasticity, Lame s equation, heat conduction equation, differential and operator equations system, two-layer weighted schemes, stability estimates, a priori estimate, fi nite elements method, numerical simulation. Many applied problems mathematical simulation are quasistationary problem (stationary for displacements and related to the need to calculate the strain-stress state of non-stationary for temperature) can be solved through the solids. In many cases, deformations are caused by use of two-layer weighted scheme [9]. The approximate thermal dilation. To study the deformations, the models of solution for the initial data and the right-hand side under thermoelasticity are used [1-4]. standard weight limits has proven absolutely stable. The basic mathematical models of thermoelasticity We have obtained priori estimate of the approximate include Lame equation for displacements and the heat solution, which is consistent with the corresponding equation. The fundamental point is that the system estimate for the solution of the differential problem. The of equations is tied up: the equation for displacement possibilities of computational algorithm are illustrated comprises volume force proportional to the temperature by the computed data on the model two-dimensional gradient and the temperature equation includes a term problem for the body of rectangular cross section with a describing the compressibility of the medium. circular cutout. In this paper, we describe a computational algorithm Problem statement. From mechanical and heat for solving problems of thermoelasticity. It is based impacts, displacement u, deformation ε and stress σ on the fi nite element approximation of the temperature fi elds occur in the elastic body. Suppose T – constant fi eld and the displacement fi eld in space [5-8]. The absolute temperature at which the body is in an initial equilibrium state, and θ – the temperature increment.
