Hybrid Triangular Plate Elements

In Section 11.1 different triangular plate elements are investigated according to Kirchhoff’s plate theory. As a result it can be stated that a triangular element is possible employing a conform approach of 5th order with 21 degrees of freedom, which has some disadvantages with respect to applications. Hence the question is raised whether it is possible in general to also receive conformity with approaches of less order and without curvatures as nodal degrees of freedom.
