Abstract :
This paper focuses on the minimization of a thin plate problem with discontinuities by means of GNC (graduated nonconvexity) algorithm. GNC applied to such an energy allows us to achieve the exact solution of this problem, and to overcome drawbacks concerning minimization achieved by a "two-steps" process based on thin membrane. Typical distortions of the latter are avoided with a little higher computational effort.
