✦ Synopsis


In this paper, we first give a justification of the specific form of the constitutive law of incompressible materials. The existence and uniqueness of the "indeterminate" pressure is established in general. In the framework of nonlinear incompressible elasticity, we then prove an existence and uniqueness result for the pure displacement boundary value problem with sufficiently small body forces.

Resum6

Dans cet article, on donne d'abord une justification de la forme que prend la loi de comportement d'un matrriau incompressible. On 6tabht l'existence et l'unicit6 de la pression "indrterrnin~e" en grnrral. On montre ensuite, dans le cadre de l'61asticit6 non hnraire incompressible, un rrsultat d'existence et d'unicit6 pour le problrme aux limites "en drplacement pur" avec des forces volumiques suffisamment petites.

The compliance as a measure of the global rigidity of a structure is classically used in optimization in the case of linear elasticity. Under the assumption of small strains and small displacements, the aim of the paper is to extend a classical compliance optimization algorithm to nonlinear elastic
