Abstract

Non-linear analysis of plates by the analog equation method J.T. Katsikadelis, M.S. Nerantzaki Department of Civil Engineering, National Technical University, Zografou Campus, GR-15773 Athens, Greece ABSTRACT The Analog Equation Method is applied to large deflection analysis of thin elastic plates. The von-K2rm£n plate theory is adopted. The deflection and the stress function of the non-linear problem are established by solving two linear uncoupled plate bending problems under the same boundary conditions subjected to "appropriate" (equivalent) fictitious loads. Numerical examples are presented which illustrate the efficiency and the accuracy of the proposed method. INTRODUCTION Many methods have been developed to study large deflections of plates. Analytic as well approximate methods have been presented over the years [1]. However, all these methods are restricted to plates of specific simple geometry and boundary conditions.
