Inter-layer loads determination in layered structures subjected to exposure to high temperatures

In the article, the bearing capacity of the three-layered plate, exposed to high-temperature is considered. (This similarity separate fuel cell structures, which is a system comprising laminated to each other three structural elements, namely, anode, electrolyte and cathode).

For this purpose, the basic hypotheses used for the mathematical formulation of the problem are set out. The mathematical model for axisymmetric deformation behaviour of multilayer design in conditions of high temperatures interface is developed.

To this, the ratios of the determined the ratios of the deformation process, taking into account the physical and mechanical properties of the plate layers are determined.

Thermal and mechanical properties of the fuel cell structure layers materials structure are modelled and approximations of the stresses and deformations are made.

As a result, the problem of buckling heated multi-layer body is solved, which is given as the Cauchy problem with the initial conditions set for its mechanical model.
