Different arbitrary shapes of plates are used in civil, marine and aerospace engineering. They may undergo large deflections due to large transverse loads and hence, the nonlinear analysis must be carried out on the structures. In view of the above an elegant finite element formulation is developed for analyzing the geometrically nonlinear static behavior of arbitrary shaped thin plates using superparametric element. This element is capable of accommodating different geometries just like isoparametric element. The efficacy of the element is shown by presenting different numerical examples.
