Hi All
The shipbuilding and offshore rig building industry has sponsored some academic institutions to look into this topic, and some of the results can be read across, with a little effort, into our field of work. Most appear to be FEA analyses, some plain elastic, others elasto-plastic.
The following related papers can be found on the Internet, which are not behind a pay-wall.

There is a repository site on the ‘Net with the following address where the papers given above with item numbers in brackets (parenthesis) can be downloaded.
just substitute the number for the XXXX
If anyone has the following paper, also done by the same team of people, but which is not yet available free on the ‘Net, I’d be obliged if you could let me know where to find it.
