    Finite Element Method for Elastic Plastic Plates. A finite element method is developed for the analysis of elastic, perfectly plastic sandwich plates. The method is formulated by means of Greenberg's complementary energy rate theorem using constant moment elements. This formulation results in a quadratic programming by: 9.
