Abstract\u00a0<\/strong><\/span><\/p>\n

\n

The present thesis deals with the asymptotic modeling of the effect of thin layers or stiffeners on the behavior of bi-dimensional plates. We have treated three different problems : in the first one, we have considered a Kirchhoff-Love plate reinforced with a thin layer of variable thickness. The second problem concerns the asymptotic modeling of the effect of an insulating stiffener on the behavior of a non-linear thermo-elastic plate. Finally, in the third work, we focus on the study of the effect of a thin layer on a Von Karman thermo-elastic plate, with a nonlinear thermal coupling. The analysis is carried out for a soft and a rigid layer.<\/span><\/p>\n

\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Making use of different asymptotic methods, we have derived approximate models for all these problems.<\/span><\/p>\n

Keywords :<\/strong><\/span><\/p>\n

We have treated three different problems : in the first one, we have considered a Kirchhoff-Love plate reinforced with a thin layer of variable thickness. The second problem concerns the asymptotic modeling of the effect of an insulating stiffener on the behavior of a non-linear thermo-elastic plate. Finally, in the third work, we focus on the study of the effect of a thin layer on a Von Karman thermo-elastic plate, with a nonlinear thermal coupling.
