Effect of Welded Properties on Aluminum Structures

A description of the project.s background, objective, scope, expectations and deliverables.


Aluminum, being lightweight, strong, rust resistant, and easily formidable, has been used in shipbuilding for many years. However, it also has some inherent short comings such as low melting point, hard to weld, deforms easily, etc. In addition, there is little engineering data on areas such as crack initiation, fatigue fracture characteristics, effect of welding on the strength of the welded aluminum structures and so on. The project.s goals are to review up-to-date research on the reduction in structural strength due to welding and provide a basis for the design of aluminum structures that will minimize the penalty on scantling selection that the reduced strength in weld regions requires. The project calls for comparing the experimental data gathered by Prof. J. K. Paik, et al, in SSC Report 451 titled .Mechanical Collapse Testing on Aluminum Stiffened Panels for Marine Applications.
