A method for performing a stress analysis of a ship structural detail using the results from a MAESTRO analysis is described. The method used was a top-down procedure where a portion of the MAESTRO model was modelled in considerable detail using a detailed finite element grid with boundary nodes matching the MAESTRO model. The displacements obtained at the boundary nodes from the MAESTRO analysis were applied to the refined model and a finite element analysis was carried out using the fmite element program VAST. The comparison of results shows that a MAESTRO analysis alone cannot determine the stress concentrations that occur in a structural detail such as an opening in a deck. When combined with a top-down procedure however, a more accurate assessment of the detail stresses can be obtained.
