Abstract:

We consider a curved thin film made of a non simple second grade material. The behavior of the film is described by a non convex bulk energy depending on the second order derivatives of the deformation. When the thickness of the curved film goes to zero, we show using $\Gamma$-convergence arguments that the quasiminimizers of the three-dimensional energy converge to the minimizers of an energy whose density has been '${\cal A}$-quasiconvexified' depending on a two-dimensional deformation and a Cosserat vector.
