Method of Solution and Computational Algorithm for Mixed Thermo-Mechanics Problem

Abstract

Abstract: In this paper we developed a method and a corresponding software system modeling steady-state thermal stress bearing elements of construction, working under the simultaneous effect of local temperatures, heat flow, heat transfer and thermal insulation. In addition, full-scale takes into account the dependence of the thermal expansion coefficient of the temperature. Impose strict energy conservation, minimization methods and the convergence of the Gauss solution of linear algebraic equations and experimental data to establish the relationship of the coefficient of thermal expansion of materials bearing structural elements of the field temperature distribution. Elaborated computational algorithm and approach is relatively universal in the sense of possibility of computational solution of steady problems of thermostressed condition of construction bearing components, which operate in condition of simultaneous existence of local temperature, thermal flows, heat exchange and heat conservation.
