Abstract
Current practice in crash analysis on maritime structures uses rupture strain as a single parameter failure criterion. The criterion assumes a plane strain condition irrespective of the actual stress state. However ship and offshore structures, exposed to actual collisions or groundings may well deform in different ways and exhibit other strain conditions where the material tends to develop strains in two directions and such strains may be significantly larger. The current failure criterion is therefore conservative and does not do justice to the actual structural capacity to withstand impact loads.
