A CONCISE FORMULATION METHOD OF HYBRID/MIXED MODELS AND ITS APPLICATIONS IN THIN PLATE BENDING PROBLEMS

In this paper, a concise formulation method of Hybriffeed modes is presented. It is derived from the weak form of physical-geomtry relation by using the bedc principle of weighted residual method to discretize the stress in an element None of variational principles is used in its simple and direct derivation process which has clear physical meanings Several thin plate bending elements are constructed Some numerical examples are also given.
