Une dérivation d’un modèle non linéaire de poutre à partir de l’élasticité tridimensionnelle. (A derivation of a nonlinear rod model from three-dimensional elasticity). (French) Zbl 0593.73046
The note deals with a method to obtain the one-dimensional nonlinear model by means of the nonlinear three-dimensional elastic model. The method of asymptotic expansion allows to determine the leading term for the stresses. The well-known nonlinear model for rods is obtained.
