摘要
We consider a second-order thin curved film whose behavior is governed by an energy made up of a first-order nonlinear part depending on the gradient of the deformation augmented by a quadratic second-order part depending on the tensor of second derivatives of the deformation. We carry out a 3D-2D analysis through an asymptotic expansion in powers of the thickness of the film as it tends to zero.
