Abstract: 
Thin elastic bilayer structures arise in various modern applications, e.g., in the fabrication of nanotubes or microgrippers. The mathematical modeling leads to a nonlinear fourth order problem with nonlinear pointwise constraint. We prove the convergence of a finite element discretization within the framework of $\Gamma$-convergence and discuss the convergence of an iterative solution method.
