Hybrid–Mixed Triangular Plate Elements

The governing equations related to Kirchhoff’s plate theory are given in Section 6. The weak formulation of the governing equations is developed applying the hybrid–mixed principle of work according to Section 16, where the discretization employing rectangular elements is represented. Subsequently the work equations are picked up again and are extended with respect to the demands on triangular elements. By analogy with Section 17 the element is split into element domain, element boundary and interface, cf. Figure 18-1.
