Thermomechanical analysis of hotplates by FEM
This paper deals with the finite element model for the three-dimensional analysis of thermally isolated hotplates. These hotplates can be used as gas sensors. Our calculations result in the temperature distribution, the stress and displacement field. The stress and displacement fields are calculated from the thermal results (coupled analysis). Calculations were made in different cases of boundary conditions. The results were discussed with respect to the initial experimental findings. The problem is very difficult, hence the present results are qualitative and further examination is needed.
