Towards efficient implementation of hybrid equilibrium plate elements

This paper summarises the formulation of a hybrid equilibrium plate element based on semi-continuous fields of internal stresses and edge displacements which has the capability to produce statically admissible fields of stressresultants. Implementation issues are discussed and advantage taken of the triangular shape of the constitutive primitive elements. An example of a plate with membrane actions is included to illustrate possibilities for p-type convergence.
