Abstract.
The plate bending or Babuska paradox refers to the failure of convergence
when a linear bending problem with simple support boundary conditions is
approximated using polygonal domain approximations. We provide an
explanation based on a variational viewpoint and identify sufficient
conditions that avoid the paradox and which show that boundary conditions
have to be suitably modified. We show that the paradox also matters in
nonlinear thin-sheet folding problems and devise approximations that
correctly converge to the original problem.
