Aspects of a numerical procedure used to assess the response of flat and stiffened plates used in ship-type structures under static and dynamic loading are described. The equations of equilibrium of flat and stiffened plates are solved in the large-deflection elastoplastic range in a discretised form using the dynamic relaxation method on an interlacing finite-difference grid. Solutions may be obtained using either the Marguerre equations or the equations for beam-columns. A variety of boundary conditions may be considered. In static analyses material nonlinearity is modelled according to von Mises' criterion in conjunction with the Prandtl-Reuss flow rule whereas in dynamics problems Perzyna's formulation for elastic/visco-perfectly plastic materials is used to model plastic flow. Examples of results are given for various geometries and applied loads. Copyright (C) 1996 Civil-Comp Ltd and Elsevier Science Ltd.
