[Une approche riemannienne vers des mesures des deformation en élasticité non linéaire]
L'énergie isotrope de Hencky est une mesure naturelle de la distance du gradient de déformation à l'ensemble des rotations rigides
The isotropic Hencky strain energy appears naturally as a distance measure of the deformation gradient to the set
In deriving the result, geodesics on
