However, the rise of residual stress caused by the discontinuity of nature of this type of sandwich material, like incompatibility of the characteristics, which creates a risk of rupture of the structure and limited the using range of these types of materials. In this paper, we study the bonding of ceramic and metal and we will focus on the role played by the ceramic element in the stress state of ceramic/ metal interface and the stresses evaluation by Finite Element when the structure is subjected to thermo-Mechanical loading.

The FGM plate is simply supported and subjected to sinusoidal and uniform load. The Poisson\'s ratio is kept constant. The results obtained compared to those available in the literature show the convergence, the exactitude and the efficiency of the method used with various power index of the materials.

different types of materials, two parts have been developed in this study. The first part is
devoted to the study of material properties used in this work include metallic materials and
ceramic materials. This literature survey deals with general physical and mechanical
properties of metallic materials, the properties of ceramic materials. On the one hand and
on the other hand we present a method for the preparation of a metal-ceramic.
The second part of this work is devoted to a study by the three-dimensional numerical
finite element method and levels of the stress distribution in the composite structure
(multi-material). Effect of the nature of loading, their combination of mechanical
properties and physical metal and ceramics, temperature, distance of the interface are
highlighted.
Keywords: metallic materials properties, ceramic materials properties, materials,
sandwich-type, metal-ceramic interface, residual stresses, mechanical loading, thermal
loading, thermo mechanical loading.
