Abstract
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
elasto-plastic 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 materials is
used to model plastic flow. Examples of results are
given for various geometries and applied loads.
