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. (C) 2001 Academie des sciences/Editions scie
