Aspects of the Behaviour of Rectangular Steel Plates Under Uniaxial Compression

This paper describes an efficient finite element technique for the elasto-plastic analysis of rectangular plates subjected to uniaxial compression. Results are presented covering aspects of plate behaviour meriting further study, which serve both to demonstrate the applicability of the method and to enhance the available information on plate behaviour. The plates analysed are supported along all four edges, and the studies presented include investigations into the effects of inplane and out-of-plane boundary conditions. The results show that the general pattern of collapse behaviour of plates is similar for all configurations of boundary conditions considered, and can be economically and accurately predicted by this method from the analysis of plates of low aspect ratio. It is shown, however, that care must be exercised in the prediction of the behaviour of plates fully constrained inplane when elastic buckling stress and yield stress are nearly equal, and of fully clamped plates of low to intermediate aspect ratio.
