Abstract: By applying finite element numerical calculation, the research on the thermoelasticity of the composite structure made up of anti-corrosive coating and low carbon steel base is done. On the basis of hypothesizing a mechanical model and temperature fields, various actual service conditions are simulated, the value of internal stresses and its distribution in different parts of the composite structure, at the interface in particular, are analysed. The results obtained in the research are great value in practice.
