Linear elasticity obtained from finite elasticity by Γ-convergence under weak coerciveness conditions

The energy functional of linear elasticity is obtained as Γ-limit of suitable rescalings of the energies of finite elasticity. The quadratic control from below of the energy density W(∇v) for large values of the deformation gradient ∇v is replaced here by the weaker condition W(∇v)⩾|∇v|p, for some p>1. Energies of this type are commonly used in the study of a large class of compressible rubber-like materials.
