A method for treating nonconforming thin plate bending problems

Weak form for the thin plate bending problems is derived and the boundary parameters included. The weak form is useful in dealing with and understanding about nonconforming problems in finite element methods and other numerical methods. It can be observed that finite element method (FEM) can also be formulated from the same weak form. In addition, a new discretization scheme is introduced, which is proven by numerical results to be highly accurate and has no nonconforming problems.
