Abstract
Keywords: multilayer, composite, frame, thermal, solicitations
The paper puts in evidence the particular problems set by the calculus of the composite frames through the method of the finite elements to thermal solicitations. Using of the multilayer model can represent the repartition of the temperature in each layer through linear approximations, conveniently simplifying the problem. This method permits, for anisotropic material, to take count of the component materials properties depending on temperature.
