Abstract:

A numerical study of the thermomechanical state of rods of variable cross section in the presence of local temperature, heat flux, thermal insulation, heat transfer, and axial forces is of interest for technology and technological processes related to the strengths of elements of partially insulated structures.The rapid development of the processing of natural wealth, which faced scientists with new problems in developing adequate mathematical models of universal computational algorithms and methods, allowing a comprehensive numerical study of the thermoelastic state of partially heat-insulated structural elements of variable cross-section working in a complex thermal and force field. The relevance of these problems is also motivated by the fact that many structural elements of variable cross section work under the simultaneous action of tensile (compressive) axial force, local temperature, heat flux, heat transfer and thermal insulation.
