Optimization of internal composite reinforcements of 3D structures

The reinforcement of a 3D structure with composite panels is considered. Th e behaviour of those panels are to be optimized considering the external lo ading of the 3D structure. The study is within the framework of anisotropic linear elasticity. The 3D model takes into account the rigidity induced by , Kirchhoff-Love plate reinforcement. An optimization of the behavior chara cteristics of the composite reinforcement (density and orientation of fiber s at each point) is presented.
