Analytical Modelling of Structural Distortion in Ship Structures Produced by Welding.

Abstract

The overall objective of this research was to apply and further develop where necessary the technology for predicting distortion of submarine structure due to welding. The underlying motivation in providing this technology is that it can be used in design and construction of submarines to help determine the most cost effective weld joint designs and welding procedures. The specific objectives of the initial contract were: (1) implementation of MIT finite element computer programs for prediction of temperatures, residual stresses, and distortion due to welding; (2) evaluation of MIT computer programs on a fusion weld of two plates and comparison with results obtained by MARC-CDC finite element program; and (3) analysis of a butt welded unrestrained plate with MIT computer codes and comparison with test results.
