### Coupled thermo-structural analysis

A simply supported beam subjected to a temperature rise of 10 °C on the upper face and a temperature reduction of 10°C on the lower face, with insulated side faces – Figure 1, was modeled by plane elements using INSANE – Figure 2. The software calculated both the temperature distribution within the domain – Figure 2(a) and the displacement field by a thermo-structural analysis – Figure 2(b). The results comparison between the numerical and the analytic solutions is presented in Figure 3.
