[Reconstruction d'un champ de déplacements d'une surface à partir de ses tenseurs linéarisés de changement de métrique et de changement de courbure]
On montre que les composantes des tenseurs linéarisés de changement de métrique et de changement de courbure associés à un champ de déplacements d'une surface de doivent satisfaire certaines relations de compatibilité, qui sont les analogues « sur une surface » des relations de Saint Venant en élasticité tri-dimensionnelle.
On montre ensuite que, inversement, si deux champs de matrices symétriques d'ordre deux satisfont ces mêmes relations de compatibilité sur une surface simplement connexe, alors ce sont les tenseurs linéarisés de changement de métrique et de changement de courbure d'un champ de déplacements de la surface S.
We establish that the components of the linearized change of metric and change of curvature tensors associated with a displacement field of a surface in must satisfy compatibility conditions, which are the analogues ‘on a surface’ of the Saint Venant equations in three-dimensional elasticity.
We next show that, conversely, if two symmetric matrix fields of order two satisfy these compatibility conditions over a simply-connected surface , then they are the linearized change of metric and change of curvature tensors associated with a displacement field of the surface S.
