DG approach to large bending plate deformations with isometry constraint

We propose a new discontinuous Galerkin (dG) method for geometrically nonlinear Kirchhoff plate model large isometric bending deformations. The minimization problem is nonconvex due to the isometry constraint. present practical discrete gradient flow that decreases energy and computes minimizers satisfy prescribed defect. prove [Formula: see text]-convergence of energies global minimizers. document flexibility accuracy dG with several numerical experiments.
