Abstract
The paper describes a systematic approach to computer aided ship structural analysis. The methods are incorporated into the computer programs MAESTRO and MGDSA for the modelling and analysis of global and detail structure, respectively. The capabilities of these programs are briefly discussed. Examples of application to Canadian naval vessels are used to illustrate the described methods. The time required to undertake top/down analysis of ship structural details, particularly in generating the FE models, is still a limiting factor in using this method for fatigue and strength analysis. An improved approach to finite element analysis of ship structural details which is being developed by DREA is discussed. This new approach will significantly reduce the time necessary to create and analyze details for fatigue, strength and stability to a few hours instead of the few days that it takes at present for complex structure.
